More than three successive premature ventricular contractions are called ventricular tachycardia. This term denotes repetitiveness of the ectopic and is more sinister than isolated ectopics. Configuration of the premature ventricular contraction on the surface ECG can give a reasonable impression about the...

Tachycardia is defined as (a) active heart rate above 100. (b) resting heart rate above 100. (c) resting heart rate below 60. (d) active heart rate above 60. (e) active heart rate below 60. Explain the events that are occurring in the heart duri...

Catecholaminergic Polymorphic Ventricular Tachycardia is a rare ion channelopathy characterized by polymorphic ventricular tachycardia during exercise despite a structurally normal heart. Untreated, it has a high risk of sudden death, and delays in clinical diagnosis are common, as t...
During early diastole, defined as the interval from the opening of the mitral valve to the point of minimal left ventricular pressure, 20 percent of total ventricular filling took place at resting heart rate, but 62 percent occurred during tachycardia. Minimal pressure was significantly correlated ...

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a condition of abnormal heart rhythm (arrhythmia), induced by physical activity or stress. Mutations in ryanodine receptor 2 (RyR2), a Ca2+ release channel located in the sarcoplasmic reticu
