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.
Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or a skipped beat. They typically have no long-term complications. They most often happen naturally but may be associated with caffeine, nicotine, or ...
Those who have severe symptoms from an arrhythmia or are medically unstable may receive urgent treatment with a controlled electric shock in the form of cardioversion or defibrillation. [6] Arrhythmia affects millions of people. [4] In Europe and North America, as of 2014, atrial fibrillation affects about 2% to 3% of the population. [9]

[1] [2] It is an iatrogenic disease—an adverse effect resulting from medical treatment—that is often underdiagnosed. [1] [3] In general, the symptoms of the syndrome are a combination of decreased cardiac output, loss of atrial contribution to ventricular filling, loss of total peripheral resistance response, and nonphysiologic pressure ...
Heart rate turbulence (HRT) is a baroreflex-mediated adjustment of heart rate which acts as a counter-mechanism to premature ventricular contraction (PVC). [1] It consists of a brief speed-up in heart rate, followed by a slow decrease back to the baseline rate.

Treatment Avoidance of AV-nodal-blocking medication First-degree atrioventricular block (AV block) is a disease of the electrical conduction system of the heart in which electrical impulses conduct from the cardiac atria to the ventricles through the atrioventricular node (AV node) more slowly than normal.
