![]() Ventricular fibrillationĮlectrical signals that cause the ventricles to palpitate rather than pump normally result in ventricular fibrillation. Severe arrhythmias like ventricular fibrillation can result if it persists for longer than a few seconds. Many times, ventricular tachycardia that lasts only a few beats is not harmful. Ventricular tachycardia is a rapid, regular heartbeat that can last anywhere from a few seconds to several minutes. This type of arrhythmia is risky and calls for medical attention immediately. Ventricular arrhythmia initiates in the ventricles, also known as the lower chambers of the heart. The upper and lower chambers may begin to beat at various rates due to this. Scar or damage to the tissue may block the signal that alerts the atria to beat. The upper chambers of the heart beat 250–350 times per minute due to atrial flutter. The lower chambers do not fill completely or do not pump enough blood to the body and lungs when this occurs. The heart beats more than 400 times per minute for a person with this condition.Īdditionally, coordination is lacking between the upper and lower chambers of the heart. Atrial fibrillationĪtrial fibrillation is the most frequent form of arrhythmia. Atrial tachycardiaĪtrial tachycardia is a fast and rapid heart rate that witnesses more than 100 beats per minute. AV nodal re-entrant tachycardia (AVNRT)Ī rapid heartbeat is brought on by multiple pathways passing through the atrioventricular (AV) node. Impulses pass through both usual and additional pathways, enabling the impulses to move through the heart quickly and making it beat erratically. Accessory pathway tachycardia (bypass tract tachycardia)Ī rapid heartbeat is brought on by an abnormal electrical connection or pathway between the atria and ventricles. It frequently affects young people and is typically not dangerous. It may occur while engaging in strenuous physical activity. This results in extra heartbeats, causing tachycardia. The malfunction in the electrical signals that start in the upper chambers and move to the lower chambers of the heart gives rise to paroxysmal supraventricular tachycardia (PSVT). Paroxysmal supraventricular tachycardia (PSVT) Supraventricular arrhythmia commences in the upper chambers of the heart or atria. Tachycardia is a resting heart rate of more than 100 beats per minute. People who are young or physically fit may experience lower heart rates in some cases. Types of Arrhythmias Bradycardiaīradycardia is a resting heart rate of less than 60 beats per minute. Dizziness, faintness and other symptoms could manifest. However, a persistent irregular rhythm might indicate that the heart is not supplying the body with enough blood. The heart also tends to skip a beat once in a while, which is normal. The rate slows down during rest and sleep. The heart rate is likely to elevate while exercising and performing physical activity. ![]() ![]() The pattern and the timing of the heartbeat will be aberrant. Arrhythmia, commonly referred to as irregular heartbeat, is an abnormal rhythm of the heart. ![]()
