EASY ECG- powerpoint presentations

“The ECG learning modules are designed to help you learn how to look at ECG rhythm strips and interpret them. Is the strip the normal rhythm of the heart — normal sinus rhythm? Or an abnormal and potential dangerous rhythm like ventricular fibrillation? You will also be introduced to the 12-lead ECG and learn how to look for signs of an acute myocardial infarction” – UCSF SCHOOL OF MEDICINE

Electrocardiographic Rhythms-Biomedical terminology of ECG

Normal sinus rhythm

This is a normal rhythm, and is not of diagnostic significance unless the rate, which ranges from 60 to 100 beats per minute, is not appropriate for the clinical setting.

Sinus tachycardia

This rhythm differs from normal sinus rhythm only in that the rate is above 100 beats per minute. The differential diagnosis is extensive. Common causes are anxiety; physiological stress such as hemorrhage, dehydration, sepsis, and fever; and hyperthyroidism. Correction of the underlying cause, if necessary, is recommended.
