Pacemakers & ICDs: Advanced Heart Rhythm Care

At Hawaii Heart Associates, we offer expert care for patients with irregular heart rhythms, including those that are too slow or dangerously fast. Our board-certified cardiologists specialize in the implantation and management of pacemakers and implantable cardioverter defibrillators (ICDs)—small, life-saving devices that help keep your heart beating safely and steadily.

These devices are implanted using minimally invasive procedures at hospitals across Hawaii. A pacemaker helps control slow heart rates, while an ICD is designed to detect and correct dangerous fast rhythms that could lead to sudden cardiac arrest.

We’re with you every step of the way—from your first consultation to long-term monitoring and support. Our team ensures that each patient receives personalized, thorough care for the best possible heart rhythm management and overall heart health.
