Doctor gives cardiac stress test to everyone of his patients. Don't know what he's looking for. What's a less demanding heart pounding type test/scan?

Stress test. Why don't you discuss with the doc why he thinks you need a/the test and what decisions the test results will provide for. If you don't like the answer or if it isn't forthcoming, you might look for someone who will communicate with you. Treadmill tests are not a big deal and neither are heart scans but if you don't need the test, you don't need the test.
