Supraventricular tachycardiaCryosurgery: Cryosurgery (cryotherapy) is the use of extreme cold in surgery to destroy abnormal or diseased tissue.DermNet NZ – Cryotherapy The term comes from the Greek words cryo (κρύο) ("icy cold") and surgery (cheirourgiki – χειρουργική) meaning "hand work" or "handiwork".Cystic tumour of the atrioventricular nodal region: Cystic tumour of the atrioventricular nodal region is a very rare tumour of the heart in the region of the atrioventricular node. It is also known as mesothelioma of the atrioventricular node.TachycardiaAutomated ECG interpretation: Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.Paroxysmal tachycardiaAtrial tachycardiaChrysler TEVanVentricular dyssynchrony: In cardiology, Ventricular dyssynchrony is a difference in the timing, or lack of synchrony, of contractions in different ventricles in the heart. Large differences in timing of contractions can reduce cardiac efficiency and is correlated with heart failure.Presyncope: Presyncope is a state consisting of lightheadedness, muscular weakness, blurred vision, and feeling faint (as opposed to a syncope, which is actually fainting). Presyncope is most often cardiovascular in etiology.Proarrhythmia: Proarrhythmia is a new or more frequent occurrence of pre-existing arrhythmias, paradoxically precipitated by antiarrhythmic therapy, which means it is a side effect associated with the administration of some existing antiarrhythmic drugs, as well as drugs for other indications. In other words, it is a tendency of antiarrhythmic drugs to facilitate emergence of new arrhythmias.Primary ventricular fibrillation: Primary ventricular fibrillation (PVF) is an unpredictable and potentially fatal arrhythmia occurring during the acute phase of a myocardial infarction leading to immediate [and, if left untreated, leads to sudden cardiac death] within minutes. In developed countries, PVF is a leading cause of death.Lorcainide
