Sinus Tachycardia. Ur valuable opinion.

Dear Sir/ Madam, Iam a healthy individual, teetotaler. I have been feeling fatigue for two days and then was given mofoxin and a anti inflammatory meds and Ascoril plus for cough. After five days as I had normal temp 96.9 to 98.5, once 99.3. The doc gave me drips with antibiotics morning and evening 4 bottles and changed my meds to Delamox 625 I took one dose of it after first drips . Since the second drips my heart rate has increased and even reached 229 once and on deep breathing or movement it always crosses 120 and also stabilizes below 100 on rest. My left elbow shows some mild throbbing pain. My SpO2 is around 96 n I have tested covid -ve. My chest c ray is normal and shows prominent bronchio vascular markings. As I consulted a casualty they did ECG and told I have Sinus Tachycardia and given ZOSA 40, Ascovent, Montec LC and vitamin C. I have been advices Thyroid, Lipid profile and CBC. I want to do a complete master check up. Please advice with ur valuable opinion. Thank U
