This document discusses definitions of hypertension, hypertensive emergencies, and malignant hypertension. It notes that hypertensive emergencies involve systolic blood pressure over 180 or diastolic over 120 with end-organ damage. Malignant hypertension is defined as a sudden increase in blood pressure in a patient with underlying hypertension, or sudden onset of hypertension in a previously normotensive individual, with irreversible organ damage. Preeclampsia, occurring in 5-7% of pregnancies after 20 weeks, is characterized by new onset hypertension and proteinuria, with risk of seizures. Treatment options discussed include delivery, magnesium sulfate, labetalol, nifedipine and hydralazine.
This document provides an overview of cardiac arrhythmias for medical students. It begins by describing the normal conduction pathways in the heart and normal sinus rhythm on an electrocardiogram. It then classifies arrhythmias as rapid and regular, rapid and irregular, slow and regular, or slow and irregular based on heart rate and rhythm. Various types of tachycardias and bradycardias are defined, along with their typical electrocardiogram presentations and common causes. Causes, presentations, and treatments of atrial fibrillation, atrial flutter, supraventricular tachycardia, Wolff-Parkinson-White syndrome, heart block, and ventricular tachycardia are summarized. Catheter ablation techniques
The document discusses guidelines for the treatment of hypertension. It provides a history of changes to major hypertension guidelines over time, including changes in target blood pressure levels and recommendations for first-line treatment options. It also reviews compelling indications for specific antihypertensive drug classes based on concomitant diseases or conditions. The guidelines emphasize lifestyle modifications and use of diuretics, ACE inhibitors, angiotensin receptor blockers, or calcium channel blockers as preferred initial treatment options for most patients with hypertension.
Hypertension, or high blood pressure, has been documented as far back as 2600 BC. It was not until the early 18th century that methods for measuring blood pressure were developed. Blood pressure is determined by cardiac output and systemic vascular resistance. Sustained elevated blood pressure is defined as hypertension. Primary hypertension has no identifiable cause, while secondary hypertension is caused by an underlying condition. Lifestyle modifications and medication are used to treat hypertension and reduce complications like heart disease, stroke, and kidney damage. Accurate measurement and long-term management require a collaborative approach between patients and healthcare providers.
This document discusses hypertension, or high blood pressure. It notes that hypertension affects around 50 million people in the US. The main types are primary hypertension, which has no known cause, and secondary hypertension, which is caused by another disease like kidney disease. Risk factors for hypertension include genetics, family history, obesity, stress, alcohol, sodium, tobacco, and age. Untreated hypertension can lead to heart attack, stroke, kidney failure, and vision loss. African Americans have a higher risk than other populations. Treatment involves lifestyle changes and medication, with the goal of controlling blood pressure.
