Overview
The symptoms of ventricular tachycardia will depend on the ventricular rate, the duration of tachycardia, and the presence of underlying disease. In general, the symptoms include palpitations, lightheadedness, syncope, dyspnea, chest pain, cardiac arrest. Symptoms related to underlying heart disease include dyspnea at rest or on exertion, orthopnea, paroxysmal nocturnal dyspnea, chest pain, edema. Precipitating factors maybe exercise, or emotional stress. In patient presented with VT clinical history should be taken about coronary heart disease, valvular heart disease (mitral valve prolapse), congenital heart disease, thyroid disease, acute kidney injury, Chronic kidney disease, electrolyte abnormalities, stroke, embolic events, lung disease,epilepsy (arrhythmic syncope can be misdiagnosed as epilepsy), alcohol, illicit drug use, and use of over-the-counter medications causing QT prolongation and torsades de pointed. It is important to notify about the family history of SCD in first degree relatives, repetitive spontaneous pregnancy losses (concerning cardiac channelopathy), IHD, hypertrophic cardiomyopathy , dilated cardiomyopathy, ARVC, congenital heart disease, cardiac channelopathies( Long QT, Brugada, Short QT, CPVT), conduction disorders, pacemakers/ICDs, and Neuromuscular disease associated with cardiomyopathies (Muscular dystrophy, epilepsy).
History
- For patents presenting with VT, history of underlying heart disease, other comorbidities, medications, and family history of SCD in first relative should be taken.
Bellow table shown clinical history related to VT:
Symptoms
- Ventricular tachycardia can be symptomatic or asymptomatic.
- Common symptoms of ventricular tachycardia include:[3][4]
