During the last few years, portable ecg machines have gained popularity in a variety of healthcare settings. These devices are useful for patients who present sudden complaints of chest pain or arrhythmias and can help physicians diagnose them in the hospital or at home. Similarly, if you are scheduled for surgery in the future and have cardiac disease, an ECG can give your doctor a clear picture of your heart condition so that they can safely perform general anesthesia.
ECG Monitoring for Athletes: Enhancing Performance and Preventing Injuries
A full ECG monitor requires placing electrodes on the chest or four extremities (right arm, left arm, right leg, and left leg). These sensors are connected to an ECG machine via wires that read the electrical activity of the heart and then record and print it for the physician’s analysis. Generally, the full setup has wet sensors that require the use of conductive gel to increase conductivity between the skin and the sensor. Some mobile ECG devices have a more compact version of the setup that allows for more flexibility and less intrusive monitoring. For example, the Zenicor ECG 2 is a single-lead handheld device that records the ECG when pressed by the user’s thumb for 10 seconds and then displays the results on a smartphone.
Aside from detecting arrhythmias, it can also detect coronary artery disease which happens when fatty substances build up inside the arteries and block blood flow to the heart. These conditions can lead to serious complications if not diagnosed early on. With the advancement of technology, these devices are now available to be used at home and can help you save time and money in getting your ECG done in a comfortable setting.
