Long QT syndrome is a condition that affects the electrical system of the heart. It causes a delay in how the heart recharges between beats, which can increase the risk of abnormal heart rhythms. These rhythm changes can sometimes lead to fainting, seizures, or in rare cases, sudden cardiac arrest. Patients who have been diagnosed

An electrocardiogram, usually shortened to ECG, is a simple test that records the electrical activity of the heart. Cardiologists use it to check how regularly the heart is beating and whether the electrical signals that control each heartbeat are working as they should. An ECG is one of the most commonly used tests in cardiology.

Heart valve disease is a condition that affects one or more of the valves inside the heart. These valves control the direction of blood flow as it moves through the heart’s chambers and out to the rest of the body. When a valve does not open or close properly, the heart has to work harder

An ECG test is a simple and effective way to check how your heart is beating. ECG stands for electrocardiogram, and the test records the electrical activity of the heart. It is commonly used to investigate symptoms such as palpitations, chest discomfort, dizziness, or breathlessness, and it also plays an important role in routine heart

Cardiac tests are used to assess how well your heart is working and to identify problems with heart rhythm, structure, blood flow, or overall function. They play a key role in diagnosing heart conditions, guiding treatment, and monitoring long-term heart health. Many patients ask what the different cardiac tests are and why one test might

A heart screening is a set of tests designed to assess how healthy your heart is and to identify potential problems before symptoms develop. It focuses on early detection, helping spot risk factors or hidden heart conditions that could lead to more serious issues if left unchecked. Many people choose heart screening for reassurance, especially

Atrial fibrillation, often shortened to AF, is the most common type of irregular heart rhythm seen in adults. It affects how the heart beats and how efficiently blood is pumped around the body. Some people notice symptoms straight away, while others may have AF for years without realising it. We regularly assess patients who have

Heart disease is a broad term that describes a range of conditions affecting the heart and blood vessels. It is one of the most common health concerns in the UK and a leading cause of illness worldwide. Despite this, many people are unsure what heart disease actually means, how it develops, and what symptoms to

A heart attack occurs when the blood supply to part of the heart muscle becomes suddenly blocked. Without oxygen-rich blood, the affected area of the heart begins to suffer damage, and if the blockage is not treated quickly, this damage can become permanent. Many people know what a heart attack is, but fewer understand how

The term arrhythmias refers to any irregularity in the way the heart beats. A healthy heart beats in a steady, coordinated rhythm, but with an arrhythmia, the heartbeat may become too fast, too slow, or uneven. Some arrhythmias are harmless and barely noticeable, while others may cause symptoms that need medical assessment. Many patients come
