    There are no formal diagnostic criteria for TIC. Thus, TIC is typically diagnosed when (1) tests have excluded other causes of cardiomyopathy and (2) there is improvement in myocardial function after treatment of the tachycardia or arrhythmia. [1] [5] [6] Treatment of TIC can involve treating the heart failure as well as the tachycardia or ...

    CCBs of the dihydropyridine group, as well as flunarizine, predominantly cause reflex tachycardia as a reaction to the low blood pressure. [4] [5] [6] Other potential symptoms include: nausea and vomiting, a decreased level of consciousness, and breathing difficulties. [2] Symptoms usually begin within 6 hours of taking the medication by mouth. [2]

  4. Supraventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Supraventricular_tachycardia

    Junctional ectopic tachycardia (JET) is a rare tachycardia caused by increased automaticity of the AV node itself initiating frequent heartbeats. On the ECG, junctional tachycardia often presents with abnormal morphology P-waves that may fall anywhere in relation to a regular, narrow QRS complex. It is often due to drug toxicity. [22]

    Class III antiarrhythmic drugs are potassium channel blockers that cause QT prolongation and are associated with TdP. Amiodarone. Amiodarone works in many ways. It blocks sodium, potassium, and calcium channels, as well as alpha and beta adrenergic receptors. Because of its multiple actions, amiodarone causes QT prolongation but TdP is rarely ...

    The exact cause of Inappropriate sinus tachycardia is still being debated and remains unknown. Several mechanisms have been suggested, including increased sympathetic or decreased parasympathetic drive, increased intrinsic heart rate, dysfunctional neurohormonal modulation, ectopic sinus node activity, and beta-adrenergic receptor autoantibodies .
