Zio adhesive patch can monitor heart beat for those who suffer from heart- rhythm problems. An adhesive patch that houses wafer- thin electronics to monitor the pulse may help save wearers from one of the most common causes of sudden death. The gadget is worn on the skin for 2. The condition – arrhythmia – often goes undiagnosed and its effects can come on without warning. More than two million people in the UK suffer from some kind of heart- rhythm problem. Up to now, diagnosis has relied on detecting an abnormal rhythm with an electrocardiogram (ECG) machine. An adhesive patch that houses wafer- thin electronics to monitor the pulse may help save wearers from one of the most common causes of sudden death. This uses electrodes attached to the skin connected to a machine that records electrical activity emitted by the pulse. But rhythm problems may be transient, meaning that patients might have to be attached to an ECG for hours at a time in hospital, and often must attend repeated appointments before an episode is detected. The new Zio patch enables patients’ heart rhythm to be recorded for a full two weeks, collecting detailed information about the heart’s behaviour. Fitting the patch requires only a single visit to a hospital, after which it is kept on even in the shower and during moderate exercise. The device provides continuous monitoring and can help diagnose a range of arrhythmias, which are typically caused by faulty nerve impulses around the heart muscle, including supraventricular tachycardia – episodes of quickened resting heart rate – and Atrial Fibrillation (AF). AF is the most common arrhythmia, suffered by about one million Britons, and patients are up to five times more likely to have a stroke. The oval- shaped Zio patch is effectively a mini- ECG, housing two electrodes that monitor the heartbeat through the skin. The wireless device also houses electronics that record the data and a small button which the patient can press to record symptoms such as palpitations, feeling dizzy or blurred vision. After two weeks, the patch is sent back to manufacturers i. Rhythm in California, who collate the data and send it to the patient’s cardiologist for interpretation and diagnosis. An American study found that the Zio patch was significantly more sensitive in detecting irregular heart activity than an ECG, which uses multiple wires and typically can only be tolerated by patients for up to 2. Dr John Foran, consultant cardiologist at Spire St Anthony’s in Cheam, Surrey, where the treatment has been launched, said.
