You have asked…How do I interpret ECGs with confidence?
The expert says…
Arrhythmias are clinically important because of their ability to compromise cardiac output and oxygen delivery to the body. The level of cardiac performance during an arrhythmia depends on rate, site of origin, and duration of the arrhythmia, as well as the presence of underlying cardiac or systemic diseases that may adversely affect the patient. Consequences of an arrhythmia may be clinically undetectable, produce signs of inadequate cardiac output (eg, weakness, fainting, shock), or lead to complete collapse of the circulatory system and sudden death.
The 4 general steps for ECG assessment include evaluation of heart rate, cardiac rhythm, mean electrical axis, and assessment for patterns of chamber enlargement. The following review assesses and interprets common canine and feline arrhythmias.
A systematic approach to interpreting ECGs will ensure an accurate diagnosis. The initial steps should include evaluating paper speed and sensitivity followed by labeling the individual waveforms recorded on the ECG. Afterward, the following questions should be addressed:
This is the first installment of a two-part series outlining ECG interpretation. Part 2 will address bradyarrhythmias and tachyarrhythmias.
