Tiny pacemaker is paired with a small, soft, flexible wearable patch that sits on the patient's chest. The wearable patch detects irregular heartbeats and automatically emits pulses of light. The light then flashes on and off at a rate that corresponds to the correct pacing. After the tiny pacemaker is no longer needed, it dissolves inside the body.</blockquote>
