Diagnosis Of Palpitations
To diagnose the cause behind palpitations your doctor will firstly conduct a physical exam and listen to your heartbeat using a stethoscope. If your healthcare provider suspects a medical condition behind your palpitations they will recommend further tests to determine the cause behind the same.
This diagnostic procedure is a test that is quick and painless in nature. It measures the electrical activity of the heart by using sticky patches also known as electrodes. The electrodes are placed on the patient's chest, arms and legs while the wires connect the electrodes to a monitor that displays the results. An electrocardiogram helps in determining whether a person has a rapid or slow heartbeat.
This is a portable and easy to use ECG device that can be worn by the patient for a day or more. The device records the heart rhythm and rate while carrying out their daily activities. It helps in determining heart palpitations that aren't found during an EKG exam. Smartwatches often contain remote EKG monitoring and can be advised by a doctor.
Event recording
There might be cases when an irregular heartbeat isn't recorded while wearing a Holter monitor and the event may occur fewer times than in a week. In such cases, your doctor may recommend you to follow event recording. This requires a patient to press a button when they experience the symptoms and is usually recommended to be worn for 30 days or more until you experience heart palpitations.
Implantable loop recorder
An implantable loop recorder is a device that is placed subcutaneously and continuously monitors for cardiac arrhythmias. These are most often used in those with unexplained syncope and can be used for longer periods of time than the continuous loop event recorders. An implantable loop recorder is a device that is placed subcutaneously and continuously monitors for the detection of cardiac arrhythmias. These are most often used in those with unexplained syncope and are used for longer periods of time than the continuous loop event recorders. Electrophysiology testing enables a detailed analysis of the underlying mechanism of the cardiac arrhythmia as well as the site of origin.
This noninvasive modality uses sound waves to create pictures of the heart in motion. The test helps in showcasing the blood flow and structural problems on the heart and helps a provider in pinpointing the cause behind a heart symptom.
Blood tests
Your healthcare provider may recommend blood tests to check your hormone levels because palpitations can be caused due to an increase in the levels of hormone seen in cases of pregnancy or menstruation. The blood tests will also help in determining the levels of certain electrolytes in the blood that influence heartbeat such as potassium & calcium.
-
Complete blood count can assess anemia and infection.
-
Serum urea, creatinine to assess for renal dysfunction.
-
Other blood tests, particularly tests of thyroid gland function, are also important baseline investigations (an overactive thyroid gland is a potential cause for palpitations; the treatment, in that case, is to treat the thyroid gland over-activity)
Urine test
A urine test will help in determining the levels of electrolytes, hormones, blood cells and blood sugar levels in the body.
Urine metanephrines testing is used to help detect or rule out the presence of a rare tumor called a pheochromocytoma or a paraganglioma that releases excess metanephrines.
A stress test may be recommended by your doctor to determine the cause of your palpitations. This test allows a doctor to study your heart while the heart rate is elevated. This can be done by making the patient walk briskly on a treadmill or while taking a medication that causes an increase in the heart rate.
This modality helps in checking how blood flows through the heart. It helps in determining whether you have a blockage in the coronary artery that can result in symptoms such as heart palpitations. In this test, a contrast dye is injected into the arteries while the doctor observes the blood flow through the heart on an X-ray screen.
