PVCs can be distinguished from premature atrial contractions because the compensatory pause is longer following premature ventricular contractions, in addition to a difference in QRS appearance. [20] In some people, PVCs occur in a predictable pattern. Two PVCs in a row are called doublets and three PVCs in a rows are triplets.

The uncontrolled wave of calcium can be forced out through the cell membrane via the sodium-calcium exchanger, causing an electric current known as a delayed afterdepolarisation. Afterdepolarisations, if large enough, can trigger additional action potentials, premature ventricular contractions, or sustained arrhythmias. [15]
It can have many potential causes, including genetics, lifestyle habits, and underlying health issues. Some types of cardiovascular disease, such as some cardiomyopathies, develop due to factors ...
Digoxin is a medication used for heart failure or atrial fibrillation. [3] An electrocardiogram is a routine part of diagnosis. [2] Blood levels are only useful more than six hours following the last dose. [1] Activated charcoal may be used if it can be given within two hours of the person taking the medication. [1]
Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
Bigeminy is a cardiac arrhythmia in which there is a single ectopic beat, or irregular heartbeat, following each regular heartbeat.Most often this is due to ectopic beats occurring so frequently that there is one after each sinus beat, or normal heartbeat.
