Tremor electrocardiogram
Introduction
Overview
Overview
There are no ECG findings associated with tremor. However, tremor can mimic ventricular tachycardia on ECG and cause an artifact. It is important to obtain an ECG in patients diagnosed with tremor before starting medications like propranolol to investigate for bradycardia.
Electrocardiogram
Electrocardiogram
- Tremor can mimic ventricular tachycardia on ECG appearing as a broad QRS complex and cause an artifact. It must be differentiated by finding normal QRS complexes hidden between artifact waves and looking for unstable baseline at the beginning of the ECG recording. [1]
- Hyperthyroidism can appear as sinus tachycardia, atrial flutter or atrial fibrillation on ECG. [2]
- Stress and anxiety can cause sinus tachycardia on ECG.
- It is important to obtain an ECG in patients diagnosed with tremor before starting medications like propranolol to investigate for bradycardia. [3]
