heart block
Cardiac electrical delay
Heart block is a cardiac condition where electrical signals between the heart's chambers are delayed or interrupted, causing the heart to beat too slowly or irregularly.
Degrees range from mild (first-degree) to complete (third-degree), where the upper and lower chambers beat independently.
The doctor detected heart block on the EKG and recommended a pacemaker.
