Sir,

A 31-year-old male, with past history of non- ST elevation myocardial infarction in February 2012, presented with sudden onset right-sided weakness of one month duration. Magnetic resonance imaging (MRI) showed infarct in left middle cerebral artery territory and MR angiography showed severe left internal carotid artery (ICA) stenosis. He was taken up for diagnostic cerebral digital subtraction angiography (DSA) for further evaluation. Continuous monitoring of electrocardiography (ECG), pulse oximeter oxygen saturation (SpO 2 ), and heart rate was done as a standard protocol. Carotid angiogram revealed left ICA occlusion. Left vertebral artery (VA) catheterization was attempted as catheterization of right VA resulted in severe arterial spasm. Left VA was arising directly from aortic arch. Initial attempt to catheterize left A resulted in ventricular bigeminy. Catheter tip was withdrawn immediately. After sometime left VA catheterization was again attempted, while catheter was in-situ in left VA, ventricular bigeminy recurred which disappeared with the withdrawal of catheter [Figure 1]. Patient remained asymptomatic throughout the procedure. No fluctuations in blood pressure, SpO 2 , or sweating were noted throughout the procedure, particularly during the period of ventricular bigeminy.{Figure 1}

This patients was not on any drugs or had any metabolic abnormalities that can cause ventricular ectopic. [1] Metabolic parameters done just prior to the procedure were normal. Cardiac causes like acute and chronic ischemic heart disease, cardiomyopathy, valvular heart disease, mitral valve prolapse can cause ventricular ectopic. Though our patient had chronic ischemic heart disease, previous normal sinus rhythm and peculiarly the phenomenon of bigeminy only during vertebral artery catheterization makes the heart disease also less likely cause. Among cerebral lesions, insular stroke, cortical and diencephalic tumors are reported to cause cardiac arrhythmias. [2],[3],[4] Mechanism of ventricular bigeminy following vertebral artery catheterization in our patient is unclear. Severe spasm of right vertebral artery during catheterization by glide catheter would suggest sympathetic hyperactivity of cerebral vessels. Possibly ventricular bigeminy in our patient can be secondary to sympathetic stimulation by the catheter. Psychological factors and stress leading to upregulation and dysfunction of sympathetic system might be an additive factor. This unique observation in this patient emphasizes the importance of continuous monitoring of ECG, heart rate, and SpO 2 during any cerebral angiographic procedure.
