ECG readings can be interpreted in three ways:
• Normal reading
• Abnormal reading
• State of death
A normal heart makes systematic diagrams at regular intervals. The heart rate is 60-90 beats per minute. The time difference between the PR wave and the QRS complex is 0.12 to 0.20 seconds.
The smallest, comprehensive multi-parameter patient simulator on the market includes ECG, Respiration, Arrhythmia, 4-IBP, YSI 400/700 Temperature, and Cardiac Output. Its patented power circuitry provides amazing battery life up to 10 years without charging or changing batteries! One button operation reduces the time for setup and completing testing.
The QT interval lasts no more than 0.40 seconds, while the QRS complex lasts 0.06-0.10 seconds.

Abnormal readings indicate uneven wave intervals. Sometimes they can have irregularities without a particular pattern. The cardiologist must then read the report to understand the patient's condition.
If the QT interval is abnormally long, this indicates a risk of death. In one case longer than half the R-R wave. When the QT waves eventually lengthen and lengthen, it can mean a person's heart has stopped beating, resulting in death.
However, death did not occur due to the ECG procedure. For various reasons like heart attack or accident, the person may suffer before the examination.
It is important to know the heart, medical news and achievements to live a healthy, conscious and safe life.
