Some heart problems occur only during exercise. This noninvasive test uses sound waves to produce images of the heart's size, structure and motion. Ask your doctor if this is an option for you. Some personal devices, such as smartwatches, offer electrocardiogram monitoring. Holter monitoring is especially useful in diagnosing heartbeat problems that occur at unpredictable times. During that time, the device records all of your heartbeats. Your doctor may want you to wear a Holter monitor for 1 to 2 days. A Holter monitor is a small, wearable device that keeps track of the heart's rhythm. An ECG can show if the heart is beating too fast, too slow or not at all. Wires connect the electrodes to a computer, which displays the test results. Sticky patches (electrodes) are placed on the chest and sometimes the arms and legs. This quick and painless test measures the electrical activity of the heart.

Tests done before you get a pacemaker could include:

Blood in the space between the lung and chest wall (hemothorax).Damage to blood vessels or nerves near the pacemaker.Blood clots (thromboembolism) near the pacemaker site.Swelling, bruising or bleeding at the pacemaker site, especially if you take blood thinners.Infection near the site in the heart where the device is implanted.Request an Appointment at Mayo Clinic RisksĬomplications related to pacemaker surgery or having a pacemaker are uncommon, but could include: These devices, called leadless pacemakers, are implanted directly into the heart muscle. 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.
