Based on the symptoms of tachycardia, shortness of breath, chest pain, and occasional high blood pressure, it seems your vata dosha might be imbalanced, possibly affecting the circulatory and respiratory systems. However, an underlying Pitta aggravation could also play a role given the high blood pressure and discomfort.
Start with dietary adjustments: avoid foods that can aggravate vata and pitta—spicy, oily or overly processed meals. Favor freshly cooked, warm meals with cooling herbs like coriander, cumin, and fennel to balance pitta. Incorporate ghee in moderate amounts to help soothe vata. Hydration should be steady but not excessive.
Include herbal formulations such as Arjuna (Terminalia arjuna), known for its beneficial effects on the heart. You can take it as a powdered form, mixed with water or warm milk, twice daily after meals with honey. Ensure you consult a local practitioner for precise dosage suited to your body constitution.
Incorporate yoga and pranayama to your routine, focusing on gentle poses and breathing exercises like Nadi Shodhana (alternate nostril breathing) which calms the nervous system and potentially balances the doshas. Practice these daily in a calm environment.
Prioritize proper sleep patterns; vata can be aggravated by irregular sleeps. Lukewarm water baths added with a few drops of essential oils such as lavender or sandalwood can promote relaxation.
Although tachycardia is benign in your case officially as per the investigations, unusual or sudden changes in symptoms warrant immediate medical attention. It’s key to keep an integrated approach, maintaining regular allopathic check-ups while exploring these Ayurvedic practices.
