Practical session • Answer the following questions about ECG. ECG tracing paper •ECG tracings are recorded on grid paper. The horizontal axis of the EKG paper records time, with black marks at the top indicating 3 second intervals. Each second is marked by 5 large grid blocks. Thus each large block equals 0.2 second. The vertical axis records EKG amplitude (voltage). Two large blocks equal 1 millivolt (mV). Each small block equals 0.1 mV. Within the large blocks are 5 small blocks, each representing 0.04 seconds. Heart rate Determine the Heart Rate ____30 beats per minute ____50 beats per minute ____60 beats per minute ____70 beats per minute ____80 beats per minute ____90 beats per minute
