Interpreting Complex Arrhythmias: Part III, An Issue of Cardiac

Any type of heart disease can affect the heart’s electrical system and cause cardiac arrhythmias. The arrhythmias that result from heart disease can span the entire gamut of cardiac arrhythmias—from entirely benign premature atrial complexes to extremely malignant ventricular fibrillation. Arrhythmias are caused by a problem in this conduction system, which can make your heartbeat too slowly, too quickly, or in an irregular way. There are different types of arrhythmia, the most common are: Atrial fibrillation is the most common irregular, often fast heart rhythm. Supraventricular tachycardia (SVT) is a very fast heart rhythm. Causes of SADS in young people include viral myocarditis, long QT syndrome, Brugada syndrome, Catecholaminergic polymorphic ventricular tachycardia, hypertrophic cardiomyopathy and arrhythmogenic right ventricular dysplasia. Negative influence on the cardiac system is caused by stressful situations, malnutrition, disturbance of sleep and rest, taking of harmful substances (toxic, alcohol, narcotic).

Sometimes, after surgery, anesthesia or hypoxia, the ventricular extrasystole also develops. Ventricular fibrillation. Electrical impulses start in a fast and disordered sequence, which causes your heart to lose its ability to beat and pump blood. This typically causes cardiac arrest. An arrhythmia is an abnormal heart rhythm. Some arrhythmias can cause problems with contractions of your heart chambers by: Not allowing the lower chambers (ventricles) to fill with enough blood, because an abnormal electrical signal is causing your heart to pump too fast or too slow.

Fainting (syncope) or near fainting. Most sudden cardiac deaths are caused by abnormal heart rhythms called arrhythmias. The most common life-threatening arrhythmia is ventricular fibrillation, which is an erratic, disorganized firing of impulses from the ventricles (the heart’s lower chambers). Causes of ventricular extrasystoles.

Ventricular Tachycardia (VT) - is fast heart rhythm, that originates in one of the ventricles of the heart. Ventricular Fibrillation (VF) - is a cause of cardiac arrest with structural heart disease -- a previous heart attack or left ventricular dysfunction shown on echo or other imaging, for example -- is a cause for concern. are indicated to provide ventricular antitachycardia pacing and ventricular defibrillation for automated treatment of life-threatening ventricular arrhythmias. Narrow QRS Complex Tachycardia Dr Vijay Amarnath NIMS,Hyderabad. A history of serious cardiac arrhythmias (ventricular tachycardia or fibrillation). Less commonly, CSM can cause some atrial tachycardias to slow and terminate. Symptoms that may be caused by arrhythmia are common in Ventricular pacing was defined as wide QRS complexes without visible P waves angle differentiated sustained ventricular arrhythmias (VA) from no VA (P Another non-ischemic cardiomyopathy, which also causes cardiac also called Prinzmetal's angina, is a syndrome caused by vasospasms of the coronary arteries.
