Does Nervousness Affect An Electrocardiogram?
Welcome to Healthcare Magic and thank you for writing to us.
An electrocardiogram (or EKG) can be considered as a preliminary test to exclude cardiac diseases such as rhythm disorders, heart attacks, heart enlargement or electrolyte imbalance. As it tries to maps the impulses from the heart from 6 positions and trace it on the graph paper, there can be several ways that this tracing may be affected.
1. Position changes can affect the tracing
2. if you hold your breath, then the heart rate slows down making it look abnormal.
3. if you panic, then the rate speeds up, and in extreme cases may look like a flutter, and appear as abnormal
As other tests such as CXR and more importantly the 2D-ECHO was normal, I would not consider this too seriously and focus on getting the operation done.
Even more, the stress test was normal and if you can do that without a glitch, then there is no organic heart disease.
Of course, other tests would include getting blood tests done to check your hemoglobin, sodium, potassium levels and if they are normal, then that is all you need.
I hope that was useful.
Best Wishes.
