Final answer:
Mr. Gupta has been diagnosed with tachycardia, a condition characterized by a resting heart rate exceeding 100 bpm. Tachycardia can have various triggers and present with a range of symptoms, from none to severe like fainting. Treatment is dependent on the underlying cause and may involve medication or surgical approaches.
Step-by-step explanation:
Tachycardia: Understanding Rapid Heart Rate
Dr. Smith has diagnosed Mr. Gupta with tachycardia, which is an abnormally high heart rate exceeding 100 beats per minute (bpm) in an adult. Tachycardia can be a response to various factors such as extreme stress, where it may be triggered by stimulation from the limbic system or disorders of the autonomic nervous system. It can also be associated with more specific conditions such as fever, anemia, hypoxia, hyperthyroidism, or acute exposure to radiation.
Though a resting heart rate above 100 bpm is generally considered tachycardic, there is individual variation, and for children, a higher rate is often normal. Symptoms of tachycardia can range from asymptomatic to dizziness, shortness of breath, lightheadedness, rapid pulse, heart palpitations, chest pain, or fainting. Treatment for tachycardia is tailored to the individual and may involve medications, therapies such as ablation, or sometimes surgical interventions.
