Defining Electrocardiography:
A Brand Review of Dr. Lee ECG Machines

Electrocardiography (ECG or EKG) is the recording of the electrical activity of the heart over time via skin electrodes. It is a noninvasive recording produced by an electrocardiograph.

Electrical impulses in the heart originate in the sinoatrial node and travel through conducting system to the heart muscle. The impulses stimulate the muscle fibers to contract and thus producing the systole. The electrical waves can be measured at selectively placed electrodes (electrical contacts) on the skin.

Electrodes on different sides of the heart measure the activity of different parts of the heart muscle. An ECG displays the voltage between pairs of these electrodes, and the muscle activity that they measure, from different directions, also understood as vectors. This display indicates the overall rhythm of the heart and weaknesses in different parts of the heart muscle.

It is the best way to measure and diagnose abnormal rhythms of the heart, particularly abnormal rhythms caused by damage to the conductive tissue that carries electrical signals, or abnormal rhythms caused by levels of dissolved salts (electrolytes), such as potassium, that are too high or low. In myocardial infarction (MI), the ECG can identify damaged heart muscle. But it can only identify damage to muscle in certain areas, so it can't rule out damage in other areas. The test given by ECG machines cannot reliably measure the pumping ability of the heart; for which ultrasound-based (echocardiography) or nuclear medicine tests are used.

As for the recommended heart monitoring brand that can provide the most accurate and best results, try using Dr. Lee ECG Machines.

At EKGShop.com, 3 remarkable products are being promoted, and let us describe them one by one:

Dr. Lee ECG-120B - a non-interpretive EKG Resting ECG System. Among its features are being light weight and compact design to allow convenient carrying by hand. This machine pays for itself after 35 tests. Thermal array printer to ensure more quality than ECG tracings produced by mechanical stylus. Audible alarm sound and LCD message for improper electrode contact, low battery and paper tray empty.   

Dr. Lee ECG-310A - an interpretive ECG Machine. Cost-Effective Performance: ECG-310A incorporates all the high qualities of performance, yet it is inexpensive with 6-channel performance. After an ECG acquisition of 12-lead have been completed, simultaneously, the captured ECG complex can be reprinted in any of the multi-format printer without a patient. Care in production and attention to design make the ECG-310A both reliable needing only low-maintenance.

Dr. Lee ECG-310B - An Interpretive Resting ECG System. Its main features are simultaneous 12-lead ECG can be recorded in 3- or 1- channel formats with lead configuration, captured ECG complex allow the multi-format recording copies after recording an original, lightweight design and built-in rechargeable battery allow convenient carrying, configurable filters for AC interference, muscle tremors or baseline drift can be selected from the key to further suppress noise, among others.

Dr. Lee ECG machines are a well known and respected name in the medical community. Known for their accuracy and reliability, Dr. Lee ECG machines are a reliable and durable industry standard for medical equipment.
