ArrhythmiasDisruption of the conduction system
Premature
complex
-Usually asymptomatic.
-If symptomatic (palpitation) B-blocker
may be helpful.
-Can be a sign of hypoxia(ventricles
contract first and before the atria have
optimally filled the ventricles with
blood, which means that circulation is
inefficient).
-Same above : If symptomatic
(palpitation) B-blocker may be helpful.
Tacharrhyth
mias -Multiple foci in the atria
irregular ventricular
rate. (no P wave).
-causes:”heart
disease:CAD,HT,mitral
valve disease.”excess
alcohol (holiday heart
syndrome).
- Irregularly irregular
pulse.
-Tt:”stabilization.
“anticoagulation to
prevent embolic CVA.
- Saw-tooth waves best
seen in the inferior
leads(2,3,aVF).
-causes :”heart failure (most
common association).
”COPD “ASD.
-at least 3 different P wave
morphologies are required for Dx.
-associated with exacerbations of
COPD.
-causes :”IHD.”Digoxin toxicity.
"excessive caffeine or alcohol.
-Tx: IV adenosine (DOC).
Accessory conducion from atria to ventricle through
bundle of kent .
ORT
-causes:CAD with prior MI (most
common cause).
- classified as “sustained”: last
more than 30 s ,symptomatic,life
threatening.”nonsustained “.
No p wave
