Hi and thanks for the query, Palpitatations and infection of helicobacter pylori have actually no direct relationship. H. Pylori is mainly involved in causing gastritis and peptic ulcer disease. Eradication and control of H. Pylori should most of the relieve the symptoms associated to gastric irritation. It might be very appropriate to consult a cardiologist for advice with respect to heart problems like palpitations that could have various causes. The first thing is making a proper diagnosis and distinguishing it from anxiety. secondly, an ECG, Chest X ray and Cardiac ultrasound could be appropriate in characterizing the palpitations if effectively present. Treatment depends on likely cause and effectiveness. I would advice you book an appointment with the cardiologist for a proper clinical review and management. thanks and best regards. Bain LE, MD.
