Detailed description:

Arms:
arm 1: None arm 2: None

Interventions: intervention 1: Bisoprolol intervention 2: Atenolol
Intervention descriptions: intervention 1: Bisoprolol will be administered at a dose of 5 milligram (mg) once daily for 2 weeks. If heart rate is less than or equal to 65 beats per minute (bpm), then the initial dose will be administered for another 2 weeks. If the heart rate remains greater than 65 bpm, then the dose will be further increased to 7.5 mg once daily for 2 weeks. After 2 weeks, if the heart rate is less than or equal to 65 bpm, the increased dose will be administered for another 2 weeks. If the heart rate is still greater than 65 bpm, then the dose will be further increased to 10 mg once daily for 2 weeks. After 2 weeks, if the heart rate is less than or equal to 65 bpm, the increased dose will be administered for another 2 weeks. intervention 2: Atenolol will be administered at a dose of 50 mg once daily for 2 weeks. If heart rate is less than or equal to 65 bpm, then the initial dose will be administered for another 2 weeks. If the heart rate remains greater than 65 bpm, then the dose will be further increased to 75 mg once daily for 2 weeks. After 2 weeks, if the heart rate is less than or equal to 65 bpm, the increased dose will be administered for another 2 weeks. If the heart rate still greater than 65 bpm, then the dose will be further increased to 100 mg once daily for 2 weeks. After 2 weeks, If the heart rate is less than or equal to 65 bpm, the increased dose will be administered for another 2 weeks.
