Brief Summary:

The aim of this study is to evaluate the Safety and feasibility of atropine added during treadmill stress testing in patients with chronotropic incompetence or poor exercise capacity.

Our hypothesis is that we can increase heart rate by using atropin in these patients, so we will achieve more conclusive results.

Arm Intervention/treatment
Placebo Comparator: 1
Pateints who achieve target haert rate or conclusive test will not be given Atropine
Drug: Atropine
I.V Atropine 0.5mg up to 2 mg
Active Comparator: 2
Patients who won't achieve tarhet heart rate or conclusive results will be given Atropine
Drug: Atropine
I.V Atropine 0.5mg up to 2 mg

Primary Outcome Measures :
  1. 1- To characterize patients who can't achieve target heart rate at treadmill exercise test.2- To evaluate atropine added during treadmill stress testing in order to increase heart rate and achieave conclusive test. [ Time Frame: 1 yaer ]
