So what is an electrocardiogram (SECA ECG or EKG, shortened from the German Elektrokardiogramm) it is a drawn graphic produced by an electrocardiograph machine, which prints out on a section of portioned paper the electrical activity of the heart recorded from the time the equipment is attached. Electro, which is the first part of the word is connected with the electrical impulses or activity that are given out by the heart, Cardio is Greek for heart and Gram, has a Greek root meaning “to write”. In the US, the abbreviation “EKG” which as mentioned before is the german abbreviation is often preferred over “SECA ECG”. “SECA ECG” is used a lot in the UK and many other countries.

The Sinoatrial node is the place that the hearts bio electrical impulses come from, the bio electrical pulse, pulses through the heart’s muscle and stimulates it into a contraction. The bio electrical charge that is given out by the Sinoatrial node is then calculated by placing electrical contacts on each side of the heart. As the pulse of current travels through the heart it is recorded by the SECA ECG machine. The measurements shown on the electrocardiograph SECA ECG are then interpreted to let the health professional know what is happening through the vessel. Giving indications of the beat of the vessel and any lessening of the electrical impulse through the vessel.

If a health professional is trying to understand the pumping function of the vessel a health professional will turn to the more modern techniques of ultrasound or nuclear medicine testing. SECA ECG’s are the best way of being able to see if there is an irregular heart beat particularlly in the case of conductive tissue damage in the heart or high and low levels of dissolved salts.
