Infection near the site in the heart where the device is implanted.These devices, called leadless pacemakers, are implanted directly into the heart muscle.Ĭomplications related to pacemaker surgery or having a pacemaker are uncommon, but could include: However, some newer pacemakers don't require leads. One to three flexible, insulated wires are each placed in one or more chambers of the heart and deliver the electrical pulses to adjust the heart rate. This small metal container houses a battery and the electrical circuitry that controls the rate of electrical pulses sent to the heart. Some newer pacemakers also have sensors that detect body motion or breathing rate and signal the devices to increase heart rate during exercise, as needed. If your heartbeat is too slow (bradycardia), the pacemaker sends electrical signals to your heart to correct the beat. Some newer pacemakers don't require leads.
These wires deliver the electrical pulses to adjust the heart rate. A pacemaker has flexible, insulated wires (leads) that are placed in one or more chambers of the heart. A pacemaker is a device used to control an irregular heart rhythm.
