Cardiovascular diseases are the leading cause of death across the globe. These are diagnosed with the help of ECG. An electrocardiogram (ECG) is a graphical recording of cardiac cycle produced by heart through an electrocardiograph. An electrocardiograph translates the heart electrical activity into line tracing on paper. ECG picks up electrical impulses generated by the polarization and depolarization of cardiac tissue and translates into a waveform. The line is represented in spikes and dips form and is known as waves. ECG helps in detecting impulse produced by heart. ECG is mainly used to detect heart problems. A standard clinical ECG consists of 12 different leads. ECG is also used to know the cause of symptoms such as chest pain and palpitation with the help of ECG machine. ECG machines are medical equipments designed to measure heart rate. ECG is specifically used to measure electrical current generated through heart beat. On the basis of type of lead used, ECG machine consists of single-lead, 3-6 lead and 12 lead ECG machine. A single-lead ECG machine is used to measure basic heart rate. Single-lead ECG machines are also used to accomplish 12 lead recordings in a sequential manner.
Single-lead ECG machines are used for research, arrhythmias and educational purposes. Single-lead ECG machines are available for home, personal use and sports. Single-lead ECG machines are also use to monitor heart rate in association with exercise, sport activities and workout. Single-lead ECG machines are cost effective tools to measure and record heart rate. Single-lead ECG machines records data for longer period which helps physicians to diagnose disease in better ways. Some other types of ECG machine include 12-lead ECG, 5-lead ECG, 3-Lead ECG, wireless ECG and portable handled ECG monitors.
