Ectopic atrial rhythm (EAT), atrial tachycardia (AT) & multifocal atrial tachycardia (MAT)

…and ectopic atrial rhythm Side effect of digoxin. Heart failure. Lung disease (COPD, pulmonary hypertension, etc). Ischemic heart disease (coronary artery disease). Structural heart disease…

Aortic regurgitation

…contractile function worsens. Chronic aortic regurgitation also leads to increasing LVEDP and LAP, which in turn results in pulmonary hypertension and pulmonary edema. Table 1…

Atrial fibrillation: ECG, classification, causes, risk factors & management

…obstructive sleep apnea and chronic obstructive pulmonary disease (COPD). Moreover, certain other tachyarrhythmias predispose to developing atrial fibrillation: atrial flutter, AVNRT and AVRT (pre excitation…

ECG manifestations of left main coronary artery (LMCA) occlusion and critical stenosis

…diaphoresis, hypotension, pulmonary edema, malignant arrhythmias, and rapid progression to cardiogenic shock. Ventricular fibrillation or asystole may occur early due to the massive ischemia. Complete…

Eletrical alternans: the ECG in pericardial effusion & cardiac tamponade

…This is due to the swinging back and forth of the heart in the pericardial space. Note that tachycardia, pulmonary embolism and ischemia may also…

Pulmonary stenosis

…a paraneoplastic syndrome that occurs due to carcinomas secreting kallikrein and serotonin. In the heart, this can lead to thickening of the pulmonary valve and…

Circulatory and haemodynamic parameters

…be due to low flow, low vascular tone or both, and the appropriate action differs fundamentally between these cases. Pressures in the heart and pulmonary…

🟠 Nitroglycerin

…Hypertension, hypertensive crisis/emergency. Pulmonary hypertension. Blood pressure control. Mechanism of action Nitroglycerin provides nitric oxide (NO) that induces vasodilatation (of both arterioles and veins…
