Overview

A pacemaker is a small device placed under the skin below the collarbone that sends gentle signals to keep the heart beating at a safe rate. It is used when the heart's natural electrical system is too slow or blocked.

Cardiac resynchronisation therapy (CRT/CRT-D) helps both sides of a weak heart pump in step, improving symptoms of heart failure. An implantable cardioverter-defibrillator (ICD) watches for life-threatening rhythms and corrects them instantly.

Dr. Senthilnathan performs temporary and permanent pacemaker, CRT, CRT-D and ICD implantation, and runs regular device-check clinics.

Who may need it

  • Slow heartbeat or heart block causing giddiness, fainting or fatigue
  • Heart failure with low pumping function and electrical delay (CRT)
  • Survivors of cardiac arrest, or patients at high risk of dangerous rhythms (ICD)

What to expect

  1. Performed under local anaesthesia with light sedation, usually in about an hour.
  2. Thin leads are passed through a vein into the heart and connected to the device placed in a small pocket under the skin.

Recovery & aftercare

  • Usually 1–2 days in hospital. Avoid raising the arm on the device side above shoulder level for 4–6 weeks.
  • Keep mobile phones at least 15 cm away from the device and carry your device ID card. Attend regular device checks.
