SpletJunctional escape rhythm is a regular rhythm with a frequency of around 40–60 beats per minute.

SpletHeart and Vascular Arrhythmias Paroxysmal supraventricular tachycardia (PSVT) is a type of abnormal heart rhythm, or arrhythmia. It occurs when a short circuit rhythm develops in the upper chamber of the heart. This results in a regular but rapid heartbeat that starts and stops abruptly. What happens during PSVT?

SpletMultifocal atrial tachycardia tachycardia can be defined as the occurrence of 3 more different morphologies of P waves at a rate more than 100/min. Multifocal atrial tachycardia is sometimes called as chaotic atrial rhythm because of the variability in atrial activity. SpletThe morphology of this sinusoidal pattern on ECG results from the fusion of wide QRS complexes with T waves. Pathophysiology. Hyperkalemia induces electrophysiological changes in the myocardium leading to a series of findings on ECG. One of these ECG changes is a sine wave pattern which is a manifestation of severe hyperkalemia.
