Final answer:
Bradycardia is the most likely interpretation of the symptoms. It is characterized by a resting heart rate below 60 bpm and may be accompanied by various symptoms. Treatment depends on the cause of the bradycardia.
Step-by-step explanation:
Bradycardia is the most likely interpretation.
Bradycardia is the condition in which resting heart rate drops below 60 beats per minute (bpm). It can be caused by abnormalities in the SA or AV node, heart muscle ischemia, or diseases of the heart vessels or valves. Symptoms may include weakness, fatigue, dizziness, fainting, chest discomfort, palpitations, or respiratory distress.
Treatment depends on the underlying cause and may include a pacemaker, supplemental oxygen, or addressing metabolic or neurological disorders.
