Question

la Ciicle the hash marks on the following tracing. b How many seconds are there from one hash mak to the next? REGULAR: ATRIAL RaTE:- P-WAVES: UPRIGHT, UNIFORM, REGULAR, before each QRS: YESO NODO PR INTERVAL: QT INTERVAL: IRREGULAR: VENTRICULAR RATE NORMAL YESO NOO QRS INTERVAL NORMAL YES NO sec sec INTTERPRETATION

Answer 1

Answer) rhythm of the patient is regular. There are 3 seconds in between 2 two hash marks.

Atrial and ventricular rate are approximately 83. We calculate rate by counting the big square, then divide 300 by number of big squares or either count small squares and divide 1500 by number of small squares.

P waves is upright, uniform and regular.

PR interval is 0.16 seconds.pr interval is normal.

Qt interval is 0.40 seconds. Qt interval is normal.

Ecg is normal. Rate and rhythm are within normal range. Qt, pr intervals are of normal range.
