How do they do a stress test to check for heart problems?

An ECG is done whil. It starts with a resting blood pressure and ECG before ewalking on a treadmill or cycling at a slow speed. Your heart rate & BP are monitored, as is your ecg, while both spped and inclination are increased. If you have physical sx, the test will be stopped. If the specialist sees st segment depression it indicates you have ischemia. But there are people with normal stress tests who die next wee.
↑ Heart Blood Flow. Exercise or IV medications given to increase heart rate & blood pressure: the heart pumps harder & faster & in turn needs more blood flow. The goal is to detect severe narrowing of the visible arteries. However, atherosclerosis does not narrow arteries, clots do, & the ekg or nuclear camera only detects major qualitative differences in capillary blood flow. Thus only severe disease ever detected.

How accurately can heart problems be ruled out when you have a stress test or a treadmill test?

Stress tests. Are designed to determine if hemodynamically significant coronary blockages are present (greater than 70%) but don't tell us if CAD is present. A coronary calcium screening does that.

Can a EKG and an echo and a nuclear stress test properly diagnose heart problems?

Depends. "Heart problems" can mean different things. EKG and nuclear stress test are used to look for blockages in the vessels in your heart. They can tell you if you've had significant prior heart attacks, if the electrical rhythm is normal, and if the heart works well under stress. The echo is great at making sure all chambers of the heart move and pump well and that all the valves are working properly.
Heart Tests. EKG is a tracing of the electrical activity of the heart. Echocardiogram is an ultrasound evaluation of the heart and used to evaluate how the heart walls move as well as the valves. Nuclear stress test is used to determine perfusion of the muscles of the heart usually at rest and at stress. So, all three are heart tests. But, not the only tests used to evaluate the heart.
Many but not all. The combination that you describe can diagnose many heart issues, but you may need further tests depending on the concerns. An evaluation of longer term heart rhythms can be done with either a Holter monitor or an Event monitor, Ambulatory blood pressure monitoring, tilt table testing, etc may be indicated depending on your symptoms. Touch base with your MD for further information.

How accurate is a completed cardiac stress test in ruling out heart problems in a person with no personal or family history of heart disease?

Not very... It looks like you are trying to predict a cardiac event in someone with a low probability of cardiac disease (a healthy person) the best example I can use is this.

My92year old dad with heart problems seems so exhausted he went through stress tests and waiting for results/what can I expect?

It depends. It depends on his existing heart problems, and what the cardiologists find from his stress test. Did they let him complete it? If so, that is a good sign because it means he wasn't showing alarming ekg changes during it. If that happens, they would usually stop the test. Your best answers will come from conversation with your father's physicians.
Expect reality. Your dad saw radio started by marconi, he watched fdr win 4 presidential races, the new deal organized & instituted, social security formed, he watched ww I vets march for benefits, he watched america begin new jobs with the wpa, he has survived umpteen presidents & 7 major wars.

Can lack of exercise and constant stress cause high bp? All other tests for heart problems, kidney problems and blood problems have come back normal?

Genes and kidneys. Your genetic background and your kidney health are far more likely culprits. Your profile says you're 20-if that's correct, you need a good evaluation for possible causes as essential hypertension, which is the cause in 90% of people, doesn't usually start so early in life. Serious obesity, if present, is an important risk factor.

The. The short answer is yes, prolonged stress can lead to an increased risk of heart disease, and we are beginning to understand better that sudden severe emotional trauma can cause cardiac events and is often referred to as "broken heart syndrome" although the exact causes for this are poorly understood.
