Arrhythmia may be classified by rate (tachycardia, bradycardia), mechanism (automaticity, re-entry, triggered) or duration (isolated premature beats; couplets; runs, that is 3 or more beats; non-sustained = less than 30 seconds or sustained = over 30 seconds). [citation needed] Arrhythmias are also classified by site of origin: [citation needed]
Arrhythmias such as asystole or bradycardia are more likely in children, in contrast to ventricular fibrillation or tachycardia as seen in adults. [ 30 ] Additional causes of sudden unexplained cardiac arrest in children include hypertrophic cardiomyopathy and coronary artery abnormalities. [ 161 ]
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...
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.
Ventricular arrhythmias include ventricular fibrillation and ventricular tachycardia. [45] [46] Arrhythmias are due to problems with the electrical conduction system of the heart. [43] Arrhythmias may occur in children; however, the normal range for the heart rate is different and depends on age. [45]
Ventricular arrhythmias due to ACM typically arise from the diseased right ventricle. The type of arrhythmia ranges from frequent premature ventricular complexes (PVCs) to ventricular tachycardia (VT) to ventricular fibrillation (VF). While the initiating factor of the ventricular arrhythmias is unclear, it may be due to triggered activity or ...
People considered to be at high risk for an arrhythmia include those with organic heart disease or any myocardial abnormality that may lead to serious arrhythmias. [1] These conditions include a scar from myocardial infarction, idiopathic dilated cardiomyopathy , clinically significant valvular regurgitant, or stenotic lesions and hypertrophic ...
Patients with noncompliant ventricles and diastolic dysfunction are particularly sensitive to loss of atrial contribution to ventricular filling and have a greater chance of developing the syndrome. This includes patients with cardiomyopathy ( hypertensive , hypertrophic , restrictive ) and elderly individuals.
