Class, Please download the EXAM FIRST. We are working through all Exam questions in the YOUTUBE video lectuers.
EKG Graph Paper and the Triplets Heart Rate Method
With the Triplets HR technique we obtain a quick 'estimate' of heart rate to get an idea of the rhythm we are interpreting. So, for the HR above we would say it is less than 50 beats per minue. Please note that you always start counting with the '0' using the R wave deflection that is directly on top of a dark line of a large box.
IMPORTANT REMINDER: We can ONLY use the Triplets HR technique with REGULAR rhythms!
The first QRS complex of this irregular rhythm is on the dark line of the large box. Note where you start counting to determine the 6-second heart rate for an irregular rhythm.
Note, with this irregular rhythm there are at least 3 small boxes before the FIRST QRS complex AND the line of the LARGE BOX. In fact, in this example we see 4 small boxes. So you start your counting of 30 large boxes at the starting point containing that first QRS complex.
