Ventricular arrhythmias include ventricular fibrillation and ventricular tachycardia. [3] [7] Bradyarrhythmias are due to sinus node dysfunction or atrioventricular conduction disturbances. [8] Arrhythmias are due to problems with the electrical conduction system of the heart. [2]
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 ]
A rapid regular rhythm is more likely to be secondary to paroxysmal supraventricular tachycardia or ventricular tachycardia, and a rapid and irregular rhythm is more likely to be an indication of atrial fibrillation, atrial flutter, or tachycardia with variable block. [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.
Ventricular tachycardia (VT or V-tach) is a potentially life-threatening cardiac arrhythmia that originates in the ventricles. It is usually a regular, wide complex tachycardia with a rate between 120 and 250 beats per minute.
There are two major classes of cardiac fibrillation: atrial fibrillation and ventricular fibrillation. Atrial fibrillation is an irregular and uncoordinated contraction of the cardiac muscle of atria. It can be a chronic condition, usually treated with anticoagulation and sometimes with conversion to normal sinus rhythm.
Idioventricular rhythm, also known as atrioventricular bradycardia or ventricular escape rhythm, is a heart rate of less than 50 BPM. This is a safety mechanism when a lack of electrical impulse or stimuli from the atrium occurs. [14]
Ventricular fibrillation – Ventricular fibrillation is fibrillation of the ventricles of the heart. Rhythmic contraction is necessary for efficient movement of blood, and fibrillation disrupts this rhythm sufficiently to cause cardiac arrest. Disorders of the myocardium. Cardiomyopathy – Cardiomyopathy is a deterioration of the myocardium ...
