Who might be able to join this trial:
- Adults aged 18 or older
- People who have a confirmed diagnosis (shown in their medical records) of one of the following heart conditions:
- Atrial fibrillation (any type — paroxysmal, persistent, long-standing persistent, or permanent), confirmed by an ECG recording lasting at least 30 seconds, with symptoms such as tiredness, heart palpitations, breathlessness, chest discomfort, sleep problems, or stress
- Paroxysmal Supraventricular Tachycardia — a condition where the heart suddenly beats very fast (150–200 beats per minute) and then stops abruptly
- Ectopic Atrial Rhythm Tachycardia — a fast heart rhythm (under 250 beats per minute) originating from an unusual spot in the heart, with a specific pattern visible on an ECG
- Ventricular Tachycardia — a fast heart rhythm of 100 or more beats per minute originating in the lower chambers of the heart
- An arrhythmia requiring a specific heart procedure (involving access to the left side of the heart, including a procedure to close off a small pouch in the heart called the left atrial appendage), in people with a moderate or higher stroke risk, bleeding risk, or who cannot take blood thinners
- Mitral stenosis (a narrowing of a heart valve) requiring a specific non-surgical procedure to open the valve, confirmed by an ultrasound of the heart, with symptoms such as breathlessness, difficulty lying flat to sleep, coughing, or chest pain
- People who have read and understood the study information and have voluntarily signed a consent form agreeing to take part
Who may not be able to join:
- People with significant heart defects present from birth, such as a hole between the upper chambers of the heart or abnormalities of the pulmonary veins (a small natural opening called a patent foramen ovale does not disqualify someone)
- People who have a blood clot in the left side of the heart
- People whose atrial fibrillation is caused by a treatable underlying condition, such as an overactive thyroid or recent chest surgery
- People with a known or suspected non-cancerous tumour in the left side of the heart (called a myxoma)
- People with unstable angina (severe chest pain that is not controlled)
- People who already have paralysis of one side of the diaphragm (the main breathing muscle)
- People who cannot take blood thinners or contrast dye used in imaging procedures
- People with liver disease (including active hepatitis) or kidney disease
- People who have had a stroke or mini-stroke (TIA) in the six months before signing the consent form
- People with a malignant cancer, a blood disorder, or a life expectancy of less than one year
- People who are currently enrolled in, or plan to join, another clinical trial of a drug, device, or biological treatment that could affect this study's results
- People who are unwilling or unable to follow all study procedures and required follow-up visits
- People who are pregnant, planning to become pregnant, or currently breastfeeding
- People considered ineligible by the trial investigator for any other reason (confirm with trial site)
