Wave: a deflection of the ECG line due to any change in the electrical activity of the heart (e.g., P wave, T wave) Positive (upward) deflection: the electrical impulse is moving toward the electrode Negative (downward) deflection: the electrical impulse is moving away from the electrode...
An abnormal ECG mainly denotes a variation in the heart rate or heart rhythm. For example, an irregular QRS complex without a P wave denotes atrial fibrillation. Likewise, an elevated ST segment in an ECG is an indication of a serious heart attack. ...

P-waves: Size and shape normal. A QRS complex is periodically dropped after a single P-wave (i.e., dropped beat).Clinical ManifestationsOften occurs secondary to sinus bradycardia. Most often asymptomatic, but presenting symptomatology includes chest pain, shortness of breath, and decreased level...
In the ECG of a diabetic patient without coronary artery disease, a double T wave was observed. The ECG was normal the next day. This finding was interpreted as representing repolarization abnormalities (e. g., myocardial ischemia) by many health care workers. However, it represents an artif...

Of course, you don't want the filter to mess up the shape of the "signal" - just to remove the "noise". It's important to look at the display with and without filtering and convince yourself you like the results. In particular, the Q and S parts of the wave have frequency componen...
Although often ignored, assessment of the electrical axis is an integral part of ECG interpretation. The electrical axis reflects the average direction of ventricular depolarization during ventricular contraction. The direction of the depolarization (and thus the electrical axis) is generally alongside the...
