Premature ventricular contractions may be associated with underlying heart disease, and certain characteristics are therefore elicited routinely: the presence of signs of heart disease or a known history of heart disease (e.g. previous myocardial infarction), as well as heart disease or sudden cardiac death in close relatives.
Medications for a fast heart rate may include beta blockers, or antiarrhythmic agents such as procainamide, which attempt to restore a normal heart rhythm. [6] This latter group may have more significant side effects, especially if taken for a long period of time. [6] Pacemakers are often used for slow heart rates. [6]
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.
A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. 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 ...
In people without underlying heart disease and who do not have any symptoms, bigeminy in itself does not require any treatment. If it does become symptomatic, beta-blockers can be used to try to suppress ventricular ectopy. Class I and III agents are generally avoided as they can provoke more serious arrhythmias. [4]
Scar-related monomorphic ventricular tachycardia is the most common type and a frequent cause of death in patients having survived a heart attack, especially if they have weak heart muscle. [12] Right ventricular outflow tract (RVOT) tachycardia is a type of monomorphic ventricular tachycardia originating in the right ventricular outflow tract ...
Normal sinus rhythm and ectopic beats - premature ventricular contractions (PVC) and premature atrial contractions (PAC) shown on an EKG. Premature atrial contractions are typically diagnosed with an electrocardiogram, Holter monitor, long-term continuous monitor, cardiac event monitor, or with a smartwatch with an ECG functionality. [citation ...
The mainstays of treatment are beta blockers, which block the effects of adrenaline and other catecholamines on the heart, reducing the chance of abnormal heart rhythms developing. [2] Of all the beta blockers, nadolol has been proven to be the most effective for treating CPVT. [ 25 ]
