What factors affect ekg?

Several factors can affect an electrocardiogram (EKG or ECG) reading, including the patient's age, sex, and physical condition. Medications, electrolyte imbalances, and underlying health conditions like Heart disease can also influence EKG results. Additionally, factors such as body temperature, stress levels, and even the patient's position during the test may impact the accuracy of the EKG. Proper electrode placement and skin preparation are crucial for obtaining reliable readings.
