Is NSVT life-threatening?
NSVT is often harmless, but can develop into a more dangerous ventricular arrhythmia and cause sudden death.
What is malignant tachyarrhythmia?
Potentially malignant ventricular arrhythmias are ventricular premature complexes (VPCs) of greater than 10 per hour 10 to 16 days after acute infarction and repetitive VPCs. The most malignant arrhythmias occur with severely depressed ventricular function, but VPCs alone have independent prognostic significance.
How serious is ventricular tachycardia?
Ventricular tachycardia may last for only a few seconds, or it can last for much longer. You may feel dizzy or short of breath, or have chest pain. Sometimes, ventricular tachycardia can cause your heart to stop (sudden cardiac arrest), which is a life-threatening medical emergency.
Should I worry about NSVT?
Nonsustained ventricular tachycardia (NSVT) may trigger concern, particularly in patients with known congestive heart failure, structural heart disease, or prolonged QT interval. When NSVT occurs in patients with normal hearts, it usually has a benign prognosis.
What does non sustained VT feel like?
SYMPTOMS: Symptoms of PVCs and NSVT may include palpitations, chest pain, pre-syncope, syncope or heart failure. SYMPTOM CONTROL: NSVT is often asymptomatic but some patients experience symptoms such as palpitations, dizziness and dyspnea.
Does tachycardia damage the heart?
In some cases, tachycardia may cause no symptoms or complications. But if left untreated, tachycardia can disrupt normal heart function and lead to serious complications, including: Heart failure. Stroke.
What kind of VT does Belhassen’s VT have?
Abstract: Belhassen’s VT is idiopathic fascicular ventricular tachycardia originating from the left posterior fascicle. It is responsive to verapamil and is an ablatable VT. Belhassen’s VT is a fast rhythm originating from the left ventricle.
Where does the QRS complex of Belhassen’s VT originate?
Even though other authors had reported on ventricular tachycardias with relatively narrow QRS complex originating from the posterior fascicle, 2 it was Belhassen and colleagues who suggested this form of ventricular tachycardia as a separate entity. 3
What kind of tachycardia does Belhassen and Associates treat?
Belhassen and associates described a ventricular tachycardia responding to verapamil, 1 unlike the usual ventricular tachycardias which respond to lignocaine. It may be noted that verapamil is conventionally a drug used for treatment of supraventricular rather than ventricular tachycardia.
What is classical ECG pattern in Belhassen’s VT?
Classical ECG pattern in Belhassen’s VT is right bundle branch block pattern with left axis deviation as it originates from the left posterior fascicle.
