Single-channel ECG patch

A single-channel ECG patch is a simple and convenient way to perform an ‘ambulatory ECG’ (while you are walking around and doing your usual activities) over a period of days. This test helps your cardiologist to monitor your heart over a longer period of time and to detect any irregular heart rhythms.

Sometimes known as an ‘echo’, an echocardiogram (ECG) is an ultrasound scan that shows an image of the heart and blood vessels. It can reveal important information about the structure of your heart and how well blood is flowing through your blood vessels.

Do I need to see a cardiologist?

The leading cardiology consultants at Harley Street Medical specialise in diagnosing and treating heart and vascular conditions, and with immediate appointments available, it’s good to know that you can proceed with your treatment plan with no need to wait on a list.

Electrochardiagram (ECG)

An electrocardiogram (ECG) is a device that is used to check your heart rhythm and electrical activity. The test is often used alongside other tests to help diagnose and monitor conditions affecting the heart.

The test should be taken when you are experiencing any of the following:

  • Chest pain
  • Palpitations (suddenly noticeable heartbeats)
  • Dizziness
  • Shortness of breath

The test involves placing some electrodes on your chest, arms and legs. They will record the electrical activity generated by the sinus node, which is where the electrical impulse is formed, and its transmission to the different areas of the heart.

The device will be able to show any arrhythmias, which is where the heart beats either too slow, too quickly or irregularly. Coronary heart disease, where the hearts blood supply is blocked or interrupted by a build-up of fatty substances. Any previous or current heart attack due to the blocked heart arteries. The test will also be able to show any cardiomyopathy which is where the hear walls become thickened or enlarged.


An Echocardiogram ultrasound scan that shows an image of the heart and blood vessels. It can reveal important information about the structure of your heart and how well blood is flowing through your blood vessels. The test takes around 20 to 30 minutes to complete.

The test should be taken when you experience any of the following:

  • Shortness of Breath 🡪 It could be a sign of a valve leakage or narrowing or a weak heart muscle or blocked arteries not supplying enough blood to your heart muscle.
  • Chest Pain 🡪 It could be sign of blocked arteries, or a clot in your lungs or inflammation of the layer around your heart.
  • Palpitations 🡪 They could be signs of structural diseases of your heart muscle or valves.
  • Loss of Consciousness 🡪 It could be indicative of obstruction of the blood flow leaving the heart and going to your brain, due to a heart valve narrowing.
  • After a stroke 🡪 you should exclude clots originating from the heart, which could have migrated to the brain, or holes in the heart.
  • Prior to major surgery 🡪 if you had already heart problems in the past, in order to make sure that the heart muscle is contracting well and is able to cope with the general anaesthesia.
Exercise Tolerance Test (ETT)

The Exercise Tolerance Test records the electrical activity of your heart whilst you are on a running machine, the heart works harder and pumps more blood through the stress that is elicited. The changes in the electrical activity are recorded by a continuous ECG, it also allows to record and monitor a continuous blood pressure which can result in hypertension or hypotension. 

On the day of the test, you should arrive in comfortable clothes and trainer shoes, you will have small electrodes placed to your chest. These electrodes will record your heart activity during the exercise which entails walking and then running on a treadmill. This test will take between 10 to 15 minutes depending on the how fast you reach the heart rate that causes enough stress on the heart.

This test allows the cardiologist to assess whether you are suffering from high blood pressure. This is essential as appropriate treatment can be initiated to prevent a heart attack or stroke. 

To perform the test, a cuff will be fit around your arm and will inflate every half an hour, taking the blood pressure readings. You will be able to perform your day-to-day task without much change. After the completion an average reading will be generated and compared to a normal desired blood pressure.
