Ekg Interpretation Strips. To briefly summarize the components of a normal ekg strip it consist of components which indicate electrical events during one heart beat. How electrocardiograms work ekg strips. You must be good at ekg interpretation to be good or pass acls. An electrocardiogram or ekg is a test that records electrical activity across multiple heart beats and produces an ekg strip that is interpreted by a healthcare professional.
View all chapters in introduction to ecg interpretation. Now if we go back to the ecg tracing each wave and dip represents a piece of the heart. How to measure an ekg strip. Methods to determine heart rate the 6 second method. Waves intervals and criteria. Count the number of complexes on the rhythm strip each rhythm strip is typically 10 seconds long.
Most ekg strips are 6 seconds the graph paper has a marking on the top or bottom to indicate every 3 seconds.
Methods to determine heart rate the 6 second method. These waveforms are labeled p q r s t and u. To better distinguish specific waves and dips in the ecg strip we assign each wave and dip a letter. Each small box is 0 04 seconds and each large box is 0 20 seconds. An electrocardiogram or ekg is a test that records electrical activity across multiple heart beats and produces an ekg strip that is interpreted by a healthcare professional. Count the number of complexes on the rhythm strip each rhythm strip is typically 10 seconds long.
