Electrophysiology Study at CritiCare Asia Hospitals, Juhu
The heart beats on a precise electrical schedule, generated and conducted by its own internal wiring. When that wiring misfires - sending signals too fast, too slow, or out of sequence - the result is an arrhythmia. Electrophysiology is the branch of cardiology dedicated to studying this electrical system directly, using an electrophysiology study to map exactly where and why the signal is going wrong. At CritiCare Asia Hospitals, Juhu, it is performed in a hospital by cardiologists who have special training in heart rhythm disorders called electrophysiologists. This study helps heart rhythm specialists in Juhu, Mumbai find out the cause of irregular heart rhythms or arrhythmias.
Understanding Arrhythmias
An arrhythmia occurs when the heart's electrical impulses don't fire or travel normally, causing the heart to beat too quickly, too slowly, or irregularly. Some arrhythmias are harmless and require only monitoring; others carry a real risk of stroke, heart failure, or sudden cardiac arrest. The distinction usually can't be made on symptoms alone, which is why electrical testing - cardiac electrophysiology matters.
Conditions Treated Through Electrophysiology
- Atrial fibrillation (AF)
Rapid, chaotic electrical activity in the upper heart chambers, increasing stroke risk - Supraventricular tachycardia (SVT)
Episodes of abnormally fast heart rate originating above the ventricles - Ventricular tachycardia (VT)
A fast rhythm originating in the lower chambers, which can be life-threatening - Heart block
A delay or interruption in the signal travelling from the upper to lower chambers - Wolff-Parkinson-White (WPW) syndrome
An extra electrical pathway present from birth that can trigger episodes of rapid heart rate
Diagnostic Tools for Electrophysiology
- ECG
A snapshot of the heart's electrical activity at rest - Holter monitor
Continuous ECG recording over 24–48 hours to catch intermittent rhythm changes - Event recorder
Worn for longer stretches, activated when symptoms occur - Tilt-table test
Evaluates how heart rate and blood pressure respond to changes in posture, used when fainting is unexplained - EP study
An invasive test that maps the heart's electrical signals directly from inside its chambers, used when non-invasive tests don't fully explain the rhythm problem

What an EP Study Involves
Thin catheters are guided through a blood vessel, typically in the groin, up to the heart under X-ray guidance. Once positioned, they record electrical activity from inside the heart, pace it faster or slower, and - if the source of an arrhythmia is identified - can deliver energy to treat it in the same sitting. The test is done under sedation or, less commonly, general anaesthesia, and usually takes one to four hours; it runs longer if ablation is performed at the same time. Consult the best electrophysiologist in Mumbai at CritiCare Asia Hospitals for further information and guidance.
During the Procedure
Electrodes are placed on the chest to monitor the heartbeat, and an IV line is set up for sedation. The catheter insertion site is numbed with local anaesthetic before the catheters are threaded up to the heart. Patients are typically not in pain during an EP study, though some sensation of a faster or slower heartbeat is normal as the heart is paced - this should be reported to the care team rather than endured silently.
After the Procedure
Patients move to a recovery area for four to six hours of monitoring, with vital signs checked throughout. Most go home the same day; an overnight stay is occasionally advised depending on the procedure performed. Results are usually discussed at a follow-up appointment, once the recorded data has been reviewed.
Treatment Options after an Electrophysiology Study
- Cardiac ablation
Uses heat or cold energy to create precise scar tissue that blocks the faulty electrical pathway causing the arrhythmia - Medications
Anti-arrhythmic drugs to control rhythm or rate where ablation isn't the immediate option - Pacemaker implantation
For rhythms that are too slow - Implantable cardioverter-defibrillator (ICD)
For patients at risk of life-threatening fast rhythms

Living with a Device
- MRI safety
Many modern pacemakers and ICDs are MRI-conditional, but this must be confirmed for the specific device before any scan - Airport security
Metal detectors don't damage devices, though carrying a device ID card is advisable - Device check-ups
Periodic monitoring confirms battery status and that the device is functioning as intended - Battery life
Varies by device type and usage; replacement is planned well ahead of depletion, not as an emergency
Recovery After Ablation or Device Implantation
- Avoid heavy lifting and strenuous activity for a period following the procedure, as advised
- Keep the catheter or device insertion site clean and dry
- Watch for swelling, bleeding, or signs of infection at the site
- Resume normal activity gradually, guided by follow-up assessment
When to Seek Urgent EP Evaluation
Certain symptoms call for prompt evaluation with an electrophysiology study rather than a wait-and-watch approach. New-onset palpitations, episodes that last longer than usual, or a pattern that seems to be intensifying should not be dismissed. Fainting spells, or moments where you feel close to losing consciousness, warrant the same urgency, even if they resolve on their own. Ongoing lightheadedness or dizziness that recurs without an obvious trigger also fits this category. The threshold for evaluation drops further if you already carry a diagnosis of heart disease, since rhythm disturbances in that setting can escalate quickly and are harder to predict.
Electrophysiology Study at CritiCare Asia Hospitals, Juhu
The electrophysiology study in Mumbai at CritiCare Asia Hospitals covers the full pathway from initial rhythm assessment to definitive treatment. It includes ECG and Holter-based screening, EP studies where invasive mapping is warranted, and same-sitting cardiac ablation when the source of an arrhythmia is identified. Device implantation and follow-up, including pacemakers and ICDs, are managed within the same cardiology setup, allowing continuity from diagnosis through long-term monitoring. Care is planned around each patient's specific rhythm disorder rather than a standard protocol, with decisions on ablation versus device therapy versus medication made based on individual EP study findings.
