This abnormal transmission of impulses leads to abnormal patterns of contractions of ventricular muscles causing an irregular contraction and relaxation pattern and an abnormal cardiac cycle (Cotran, 1999). This abnoarmal cardiac cycle due to irregular transmission of impulses is what causes an irregular pulse. Ramipril is a carboxylic derivative and belongs to a class of drugs known as ACE inhibitors. Ace inhibitors are those drugs that inhibit an enzyme Angiotensin converting enzyme. The major function of this enzyme is to convert angiotensin 1 to angiotensin 2. The converted angiotensin 2 helps increase the blood pressure by several mechanisms.
