What is an Electrocardiograph (ECG) recorder?
A cardiac event recorder is a battery-powered portable device that you control to record your heart’s electrical activity (ECG) when you have symptoms.
Why ECG recorder is needed?
We know that ECG test can let your doctor look at your heart’s activity at rest and at one point in time, but heart attack is sporadic and started suddenly and nobody can predict when an attack will happen. Sometimes after you arrive at hospital, the symptom is disappeared and the doctor cannot diagnose your disease because your ECG result is normal at that time.
‘I kept feeling this pounding in my chest. My doctor suggested I wear an ECG event recorder, and soon I was put on medicine to control my fast heartbeat’, said Kay, age 61.
Kay provided a tip that ECG recorder can solve the problem mentioned above. An ECG recorder can monitor your ECG when the symptom come, then your doctor can analyze your cardiac event and find the reason of your symptom to adjust your medicines.
Specifically, not only people have symptoms such as chest pain, dizziness, faintness or feeling uncomfortable in heart need ECG recorder to monitor their health condition of heart. People age over 50 suffer from a great risk of coronary heart disease as their body function start to decay. What’s more, you may find that a great number of middle age people are sub-healthy because they have to undertake heavy burden and work hard to beat against the increasingly competitive world. This could be serious potential health hazard and these people should monitor ECG periodically to record daily cardiac condition, which can help to discover healthy problem early and get treatment started ASAP before it’s too late.
On the other hand, modern sports medicine now consider the ECG recorder as a biofeedback instrument and evaluator. From a study by Lee in 1966, it’s found that a great part of male with CAD cannot reach target heart rate in sport.
What are the risks of ECG recorders?
Wearing an ECG recorder has no risks and causes no pain. If you wear electrode patches attached to your body and test ECG just like before, the adhesive might irritate your skin. But a new method which did not ask for an electrode patches emerged -- Simply touch certain points on the surface of the recorder can give you the ECG result, which causes no pain at all.
