This is a good strip to teach rate and interval determination.</p></div></div></div><div class="field field-name-field-rate-this-content field-type-fivestar field-label-above"><div

an acute inferior wall M.I. &nbsp;The rhythm is normal sinus rhythm at 65 bpm. &nbsp;The QRS complex is slightly wide at 112 ms (.11 seconds). &nbsp;The patient did not have a bundle branch block pattern on his 12-lead ECG. &nbsp;The PR interval is .17 seconds, and the P waves are widened and have a "double peak". &nbsp;This can be a sign of left-sided heart failure, and is called P Mitrale. &nbsp;Your students should be advised not to try to diagnose acute M.I. from a monitor strip, as ST segments can be inaccurate on some types of monitors. &nbsp;However, any derangement of the ST segment on a monitor strip calls for an immediate 12-Lead ECG for confirmation.</p></div></div></div><div class="field field-name-field-rate-this-content field-type-fivestar field-label-above"><div
