Ventricular tachycardia, also referred to as V-tach or VT, is a condition characterised by a rapid heart rhythm originating in the lower chambers of the heart, known as the ventricles. To understand ventricular tachycardia, it is crucial to appreciate the functioning of the heart. The heart rhythm is orchestrated by the sinus node located in the upper chamber, the atrium. The sinus node emits electrical signals to initiate each heartbeat. However, when this process is disrupted in the lower chambers, it precipitates an increase in the heart rate to 100 beats, giving rise to ventricular tachycardia.
There are several types of ventricular tachycardia (VT), each with distinct characteristics and implications:
This is the most common type of VT. In monomorphic VT, the heart beats with a regular rhythm but at a faster rate than normal. The QRS complexes, representing ventricular contraction, appear similar on an electrocardiogram (ECG). This type can manifest as stable (when the patient is conscious) or unstable (when the patient is in serious distress).
In polymorphic VT, the QRS complexes vary in shape and amplitude. This type of VT can be associated with a normal or prolonged QT interval on the ECG. When linked to a prolonged QT interval, it is often termed "Torsades de Pointes." Polymorphic VT can be more dangerous and is frequently associated with severe heart disease or electrolyte imbalances.
This term refers to VT that persists for more than 30 seconds. Sustained VT often necessitates medical intervention to restore the heart to a normal rhythm, and can present with noticeable symptoms.
This type of VT lasts for less than 30 seconds and resolves spontaneously. While it may not pose an immediate life-threatening risk, non-sustained VT can serve as a marker of underlying heart disease, prompting further investigation.
This term is employed when VT occurs in the absence of apparent structural heart disease. Common types of idiopathic VT originate from the outflow tracts of the ventricles.
V tach occurs when there is an abnormal heart rhythm in the ventricles. While a normal heart rate typically ranges between 60 and 100 beats per minute, in ventricular tachycardia, the heart rate often exceeds 100 beats per minute. The precise cause of this condition remains unknown, although various heart-related factors may contribute, including:
Understanding these risk factors is important for both the prevention and management of VT:
Recognizing these signs is crucial for timely intervention and management. Here's a concise breakdown of the common symptoms:
Symptoms may go away on their own within 30 seconds. However, if it lasts more than 30 seconds, it can drop blood pressure, which may be fatal.
To diagnose ventricular tachycardia, a series of tests will be conducted by the doctor. Initially, a physical examination involves listening to the heart's rhythm using a stethoscope and measuring the patient's blood pressure. Subsequently, several diagnostic tests are employed to confirm the presence of ventricular tachycardia, including:

The treatment approach is tailored to each patient's specific condition and may include a variety of interventions and therapies. The medical staff's profound knowledge and unwavering commitment ensure that patients receive the best possible care for their cardiac needs.
This is an emergency care treatment in which the doctor gives an electric shock to control the rapid heartbeat. The electrical shock affects the heart's electrical signals and restores its normal function.
Doctors will provide anti-arrhythmic drugs or IVs to slow the rapid heart rate. They may also prescribe beta-blockers and calcium channel blockers to treat ventricular tachycardia.
In coronary angioplasty, the doctor inserts a stunt into the blocked artery to maintain blood flow. During the coronary angioplasty procedure, a catheter with a tiny balloon at the tip is inserted into the artery and the doctor guides it to the blocked or narrowed blood vessel. They then inflate the balloon and add a mesh-like tube into the artery, known as a stunt.
It is a portable device that monitors the heart rhythm. The surgeon places the ICD near the left collarbone and connects the wires through the veins to the heart. The device monitors the electrical signals. If it detects a rhythm change, it sends low or high-energy shocks to reset the heart to a normal rhythm.
In this procedure, the surgeon inserts catheters through an artery and guides the heart. The catheters come with electrodes at the tip, which deliver heat to make tiny scars in the heart. The procedure helps block abnormal electrical signals and restore the usual heart rhythm.
Maintaining a healthy heart is crucial for overall well-being, and one of the ways to achieve this is by preventing ventricular tachycardia. Here are some effective strategies to incorporate into your lifestyle:
Ventricular tachycardia may cause severe complications, especially the longer it lasts. These may include:

Yes, ventricular tachycardia is generally considered serious due to its potential life-threatening nature. If it persists for more than a few seconds or is accompanied by heart disease, it can lead to ventricular fibrillation, a major contributor to sudden cardiac death.
While certain forms of ventricular tachycardia, especially non-sustained VT, may spontaneously resolve without medical intervention, it is crucial to seek medical evaluation and treatment even if the episodes cease. This helps prevent future occurrences and addresses underlying conditions.
The primary cause of ventricular tachycardia is often underlying heart disease, particularly coronary artery disease and previous heart attacks that leave scar tissue. This scar tissue can disrupt the normal electrical pathways in the heart, triggering episodes of VT.
Recovery time from ventricular tachycardia treatment varies based on factors such as the treatment method employed (medication, catheter ablation, or surgery), the individual's overall health, and the presence of underlying heart conditions. For example, recovery from catheter ablation, a common treatment, can range from a few days to a few weeks for full recuperation.
In certain cases, ventricular tachycardia can be effectively cured, especially when it stems from a specific and treatable condition. Catheter ablation, for instance, can be highly successful for certain types of ventricular tachycardia. However, in the context of chronic heart disease, management rather than a complete cure may be the focus, with treatments aimed at reducing the frequency and severity of episodes.
Ventricular tachycardia is characterised by a fast but regular heart rhythm originating from the ventricles, whereas ventricular fibrillation involves erratic, disorganised impulses from the ventricles. Ventricular fibrillation is more immediately life-threatening than ventricular tachycardia, often leading to a collapse of effective heart pumping and requiring immediate medical intervention such as defibrillation.
Certainly, ventricular tachycardia can lead to cardiac arrest, particularly if it progresses into ventricular fibrillation. Sustained or unstable ventricular tachycardia can significantly impair the heart's ability to pump blood effectively, resulting in a sudden loss of heart function, consciousness, and pulse – a situation requiring prompt medical attention.
