Body systems ecg

True or false. The ecg recording the wave forms (deflections) have both an amplitude and duration

True

True or false. On an ecg recording the intervals/segments have both an amplitude and duration

False

Which part of the ecg recording that represents atrial systole

P wave

True or false. A QRS complex must have all 3 waves present to be considered normal

False

Which part of an ECG recording that represents ventricular systole

ST segment

Which part of an ECG recording that represents arterial depolarization

P wave

Which part of an ECG recording that represents ventricular repolarization

T wave

Which part of an ecg recording that represents ventricular depolarization

QRS complex

Which interval with an increased duration indicates conduction delay through the AV node

PR interval

Which segment with an increased amplitude indicates possible myocardial infarction

ST segment

Which wave with increased amplitude indicates right atrial enlargement

P wave

In a normal ECG, the QRS complex is always preceded by which interval and wave

P wave, PR interval

In a normal ECG the QRS complex is always followed by which segment then wave

ST segment then T wave

What causes artifacts on an ecg
