What is the cause of this ECG abnormality? [1]
On this ECG the only evident abnormality (apart from the AF) is the down-slopping ST segments seen in leads V4-V6, I and aVL. These down-slopping ST-segments (or reverse ticks) are characteristic of digoxin treatment. It can be difficult to distinguish this appearance from ST depression associated with an NSTEMI. In NSTEMI the ST depression is horizontal (not down-slopping). Digoxin is often used in the treatment of atrial fibrillation (especially if there’s co-existing heart failure) in the elderly population
Name and describe the cause of this ECG abnormality [1]
Cardiac tamponade occurs when a pericardial effusion causes haemodynamically significant cardiac compression. Signs include the classic beck’s triad which is comprise of; muffled heart sounds, low blood pressure and a raised JVP/distended neck veins. Another common finding is electrical alternans which is seen above, it is caused by the swinging of the heart in the pericardial fluid as it is being compressed. Common causes of pericardial tamponade include; following procedures such as post pacemaker implantation or post cardiac surgery, after trauma or due to a spontaneous bleed in anticoagulated patients
