Pleаse аnаlyze the ECG pictured belоw. The ventricular rate is apprоximately [a] beats per minute. (Please rоund your answer to the nearest 5.) The PR interval is approximately [b] seconds. (Please round your answer to the nearest 0.04 seconds. It is probably easiest to measure this in lead II) The axis is approximately [c] degrees. (Please round your answer to the nearest 15 degrees, include the proper sign, and use numbers and not words in your answer. For example, an axis of positive seventy-five degrees should be designated "+75") The rhythm is [d]. (The answer to this question is NOT "regular" or "irregular" - it is a specific rhythm.)
