Important points about cardiac enzymes

Things you should know about Cardiac markers for MI: 1)Myoglobin first comes and first goes (rises first, disappears first). (2)LDH is called “lazy enzyme” because it comes late, and goes late (rises after 24 hours and remain till 14 days).(3)Trop-I has the greatest sensitivity and specificity.(4)The investigation of choice within first hour of MI is

Pericarditis: Symptoms, Diagnosis and Treatment

Pericarditis is an inflammation of the pericardium – the sack-like membrane that contains the heart. In most cases, the illness will pass without medical intervention. In roughly 90% of patients, the cause of pericarditis is not known, but it can be infectious or noninfectious and is the most common disease of the pericardium. In this

Supraventricular tachycardia (SVT) causes, sign/symptoms & treatment

You’ll usually feel your heart suddenly start racing and going very fast, then stop or slow down abruptly.

In heart block, the heart beats irregularly and more slowly than usual, potentially stopping for up to 20 seconds at a time. This

Wolf parkinson white syndrome

This syndrome causes a specific pattern on an electrocardiogram (Wolff-Parkinson-White pattern) and is linked to an episode of rapid heart rates, such as supraventricular tachycardia (SVT) or atrial fibrillation. Wolff-Parkinson-White syndrome is a treatable medical condition. Wolff-Parkinson-White syndrome is also

Heart Attack or Sudden Cardiac Arrest: How Are They Different?

People often use these terms interchangeably, but they are not synonyms. A heart attack is when blood flow to the heart is blocked, and sudden cardiac arrest is when the heart malfunctions and suddenly stops beating unexpectedly.

The Pharmacologic Treatment of Systemic Hypertension – Antihypertensive Drugs

Rationale for Pharmacologic Treatment of Hypertension Patients with primary hypertension are generally treated with drugs that 1) reduce blood volume (which reduces central venous pressure and cardiac output), 2) reduce systemic vascular resistance, or 3) reduce cardiac output by depressing heart rate and stroke volume. Patients with secondary hypertension are best treated by controlling or removing the underlying disease
