There are many types of abnormal ECGs, each with their own list of possible causes. Some causes of abnormal ECGs are harmless, and others carry risks. Talk with your health care provider for advice specific to your situation.
the electrocardiograph
An ECG provides information about the wearer of the ECG's heartrate and rhythm of the heart. It provides information about wether it is normal or abnormal.
The RR interval of ECG vary during normal respiration because of the sinus arrhythmia.
The portion of the ECG that indicates ventricular repolarization or recovery is the t wave. It is the wave found after the QRS complex (Ventricular depolarizaton) in a normal ECG
the contraction of the ventricles
the repolarization of the atria is hidden by the QRS wave
Yes, it is appearently possible.
If the RR of 1.5 is in seconds, it is outside the normal range of 0.6 - 1 second
right bundle branch block
Between 0.6 (100bpm) and 1 second (60bpm).
what does st elve, probable normal early repol pattern mean and left ventricucular hypertrophy mean
It's because NO test is perfect! ECG's computer is very good at recognizing something not 'normal'. It may not be able to tell you exactly what's wrong, but it knows that it's not usual. That's good enough for a computer's reading. This is why you need someone who has seen many ECG to interpret it.
