A heart arrhythmia (uh-RITH-me-uh) is an irregular heartbeat. Heart rhythm problems (heart arrhythmias) occur when the electrical signals that coordinate the heart's beats don't work properly. The faulty signaling causes the heart to beat too fast (tachycardia), too slow (bradycardia) or irregularly.
AV nodal reentrant tachycardia (AVNRT), or atrioventricular nodal reentrant tachycardia, is a type of tachycardia (fast rhythm) of the heart. It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His. AV nodal reentrant tachycardia is the most common regular supraventricular tachycardia. It is more common in women than men (approximately 75% of cases occur in females). The main symptom is palpitations. Treatment may be with specific physical maneuvers, medication, or, rarely, synchronized cardioversion. Frequent attacks may require radiofrequency ablation, in which the abnormally conducting tissue in the heart is destroyed.
AVNRT occurs when a reentry circuit forms within or just next to the atrioventricular node. The circuit usually involves two anatomical pathways: the fast pathway and the slow pathway, which are both in the right atrium. The slow pathway (which is usually targeted for ablation) is located inferior and slightly posterior to the AV node, often following the anterior margin of the coronary sinus. The fast pathway is usually located just superior and posterior to the AV node. These pathways are formed from tissue that behaves very much like the AV node, and some authors regard them as part of the AV node.
The fast and slow pathways should not be confused with the accessory pathways that give rise to Wolff-Parkinson-White syndrome (WPW syndrome) or atrioventricular reciprocating tachycardia (AVRT). In AVNRT, the fast and slow pathways are located within the right atrium close to or within the AV node and exhibit electrophysiologic properties similar to AV nodal tissue. Accessory pathways that give rise to WPW syndrome and AVRT are located in the atrioventricular valvular rings. They provide a direct connection between the atria and ventricles, and have electrophysiologic properties similar to ventricular myocardium.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

8. Types of PVCs
A- According to number of ectopic focus
1.Unifocal: one site, fixed coupling intervals, same
shape
2.Multifocal: different sites of origin, different coupling
intervals, various shapes
3.Multiformed: originate in the same ectopic site with
fixed coupling intervals but their conduction through the
ventricles differ, various shapes .
•Coupling interval
It is the length of time between an ectopic beat and the
sinus beat preceding it
9.
10.
11. B- according to its frequency:
1.Isolated single
2.Couplets
3.Triplets
4.Salvos (4-6 PVCs in a row), also called
brief ventricular tachycardias.
13. C- According to Pattern
1. Every other = Bigeminy
2. Every third = Trigeminy
Ventricular trigeminy
14. D. According to relation to previous cycleD. According to relation to previous cycle
1.Early in the cycle (R-on-T phenomenon),
2.After the T wave, or
3.Late in the cycle - often fusing with the next QRS
(fusion beat).
15. R-on-T PVCs may be especially dangerous in an acute
ischemic situation, because the ventricles may be
more vulnerable to ventricular tachycardia or fibrillation.
17. 2-Ventricular Escape Beats
• Ventricular Escaped beats must have the following
qualities:
1. They must occur at the end of a pause.
2. Wide QRS complex
• 3. No 'P' wave will precede the ventricular beat.
18. 3. Ventricular Parasystole
• Non-fixed coupled PVCs where the inter-ectopic intervals
(i.e., timing between PVCs) are some multiple (i.e., 1x,
2x, 3x, . . . etc.) of the basic rate of the parasystolic focus
• PVCs have uniform morphology unless fusion beats
occur
19. 4. Ventricular Tachycardia
1.Sustained (lasting >30 sec) vs. nonsustained
2.Monomorphic (uniform morphology) vs.
polymorphic (Torsade-de-pointes)
3.Presence of AV dissociation (independent atrial
activity) vs. retrograde atrial capture.
4.Presence of fusion QRS complexes (Dressler
beats).
22. Polymorphous ventricular tachycardia (Torsade
de pointes).
• Tachcardia
• Wide QRS complexes with multiple morphologies
• Changing R - R intervals
• The axis seems to twist about the isoelectric line
• it is important to recognise this pattern as there are a number of
reversible causes
– Heart block
– Hypokalaemia or hypomagnesaemia
– Drugs (e.g. tricyclic antidepressant overdose)
– IHD
23. 5- Ventricular fibrillation
• Bizarre, irregular, random waveform
• No clearly identifiable QRS complexes or P waves
• Wandering baseline
24. 6- Ventricular flutter
•Ventricular 'flutter' is a bizarre sine-wave like
rhythm, and usually degerates into ventricular
fibrillation. You won't see it often (or for long).
25. • 7. Idioventricular Rhythm
• A "passive" escape rhythm that occurs by
default whenever higher-lever pacemakers in AV
junction or sinus node fail to control ventricular
activation. Escape rate is usually 30-50 bpm
(i.e., slower than a junctional escape rhythm).
• Seen most often in complete AV block with AV
dissociation or in other bradycardic conditions.
