Diagnosis

Diagnosis

To diagnose palpitations, a health care provider will do a physical exam and listen to your heart using a stethoscope. The exam may include looking for signs of medical conditions that can cause heart palpitations, such as a swollen thyroid gland. You will likely be asked questions about your medical history.

If your doctor thinks that palpitations are caused by an irregular heartbeat or other heart condition, tests might include:

  • Electrocardiogram (ECG or EKG). This quick and painless test measures the electrical activity of the heart. Sticky patches (electrodes) are placed on the chest and sometimes the arms and legs. Wires connect the electrodes to a computer, which displays the test results. An ECG can show if the heart is beating too slow, too fast or not at all.
  • Holter monitoring. This portable ECG device is worn for a day or more to record the heart’s rate and rhythm during daily activities. It’s used to detect heart palpitations that aren’t found during a regular ECG exam. Some personal devices, such as smartwatches, offer remote ECG monitoring. Ask your health care provider if this is an option for you.
  • Event recording. If you don’t have irregular heart rhythms while you wear a Holter monitor or if the events occur less than once weekly, your health care provider might recommend an event recorder. You press a button when symptoms occur. An event recorder is typically worn for up to 30 days or until you have an arrhythmia or symptoms.
  • Echocardiogram. This noninvasive exam uses sound waves to create moving pictures of the heart in motion. It can show blood flow and structure problems with the heart.

How to Prevent Palpitations

Reduce Stress

Limit Alcohol

Quit Smoking

Exercise Regularly

Avoid medications that act as stimulants

Manage Your BP & Cholesterol

Follow a healthy diet

Treatment

Unless the palpitations are caused by a heart condition, heart palpitations rarely require treatment. Instead, a health care provider might recommend taking steps to avoid the triggers that cause palpitations.

If palpitations are caused by a heart condition, such as an irregular heartbeat (arrhythmia), treatment will focus on correcting the condition.

Any diagnosis begins with a clinician taking a history & physical examination.

ECG

One of the first baseline tests performed is an ECG (Electrocardiogram). This looks at the electrical activity from the heart at that moment in time. If symptoms are intermittent, an ECG will not detect the issue & a longer period of heart monitoring may be required.

External Heart Monitors (Holters)

Heart monitors can be used from 24 hours up to 14 days. The device may come with a button to push to register symptoms and/or the patient may be asked to keep a diary of times they experienced symptoms. Symptoms can then be correlated with the recording on the heart monitor.

Kardia

This is a novel heart monitor that connects via Bluetooth to your phone or tablet. There are 2 versions, one will take a basic reading of the heart rhythm which can be saved & either sent to Kardia themselves for a paid interpretation or you save the recordings to show to your GP or Cardiologist. The more advanced version will take a limited ECG recording (a full ECG shows 12 different recording strips, this device can show 6). The advantage of this device is that you keep it with you and you perform a recording when you have symptoms. You’re not reliant on the 1-14 day window of a heart monitor.

Smart Watches

The Apple Watch Series 7 was the first of now many with clinical grade heart monitoring properties approved by the FDA in America. Many alternatives are available, including those from Samsung, Fitbit & even Google. These are ideally suited to detecting Atrial Fibrillation but can detect other issues to a certain extent. If non AF heart problems, then these are probably not as good as External Holter Monitors.

Implantable Loop Recorders

The current version of these devices are small slim (0.5cm x 5cm – aprox.) units that are injected under the skin with the use of local anaesthetic. They connect to larger monitor, normally placed on the bedside which sends information collected to your medical team. The batteries on these devices can last up to 3yrs. These allow for capturing of infrequent episodes, especially those associated with blacking out.

Medical Treatments

Treatments will depend on the actual diagnosis & symptoms experienced, so not all options can be fully explained in this limited area.
