Option (b).

Heart is the pumping organs of the body. Human heart is divided into four chambered two auricles and two ventricles. The excess intake of the antidepressant drugs may inhibit the heart functioning.

Cardiac toxicity may be defined as the condition in which heart is damaged by the harmful chemicals. The sodium ions channels are important for the conduction of the heart cells. The fast blockage of sodium ions can cause the condition tricyclic antidepressant (TCA) overdose shown by the patient.
