Your symptoms of a fast heartbeat, easy tiredness, and occasional need to take deep breaths could be related to heart or lung issues, or possibly side effects from medications like Bisoprolol, which is used to treat high blood pressure and heart conditions.

🩺 Possible Causes

• Your symptoms might indicate your heart is working harder than usual, which can happen with conditions like hypertension or angina.
• Side effects of medications such as Bisoprolol include tiredness and changes in heart rate or breathing.
• Respiratory issues or anemia could also cause these symptoms.

⚠️ When to Seek Urgent Care

• If you experience chest pain, severe shortness of breath, fainting, or worsening symptoms, seek emergency care immediately.

🩺 Recommended Next Steps

• Consult a cardiologist (heart specialist) to evaluate your heart function and medication effects.
