** Thanks for contacting with your health concern 1. Although verapamil is given in supraventricular arrhythmia [most widely used] but because is associated with serious ADR [adverse drug reaction] like slow heart rate, hypotension, dizziness, liver toxicity, heart failure, AV block thus it is wise to remain under the constant supervision of your cardiologist and discuss with him about your concerns. PS. You can go for the second opinion 2. presently I believe it is the anxiety cycle which is causing further anxiety to the heart, i.e. irregular heartbeat [arrhythmia] is causing significant fear/anxiety and the further worsening of the symptoms. PS. check with your cholesterol and possible chest X-ray to exclude any heart disease. 3. If any underlying heart condition is ruled out, you will be more confident that you are healthy, and start with: A. cognitive and behavioral strategies and especially nutritional strategies, like i. practice relaxation techniques like yoga, meditation but also Pranayam which will strengthen the relaxation response of the body. ii. Stretching Yoga poses [Dhanurasana, Matsyasana, Janu Shirsasana, Paschimottanasana, Hastapadasana], hot shower and massage are simple techniques to overcome muscle tension from anxiety. iii. Apple, almond, banana, broccoli, cantaloupe, melon, carrot, cashew nut, corn, cauliflower, grapes, guava, lemon, mango, orange, pineapple, soybean, spinach have antioxidant and detoxifying properties so take them in plenty.
