An ECG can help detect:
- arrhythmias – where the heart beats too slowly, too quickly, or irregularly.
- coronary heart disease – where the heart's blood supply is blocked or interrupted by a build-up of fatty substances.
- heart attacks – where the supply of blood to the heart is suddenly blocked.
Can you have heart failure with a normal echocardiogram?
Heart failure in patients with a normal ejection fraction is generally referred to as heart failure caused by LV diastolic dysfunction (ie, diastolic failure). Such a clinical definition of diastolic failure requires (1) the presence of signs and symptoms of heart failure and (2) a normal LV ejection fraction.Does a normal echocardiogram mean my heart is fine?
What Do My Echocardiogram Results Mean? After your test, your doctor will go over your results with you. Normal results mean that your heart and its valves are working the right way, and the amount of blood your heart pumps out is normal.Do heart problems show up in blood tests?

It could be a lung disorder, such as a blood clot to the lungs, known as a pulmonary embolism. Additionally, other causes of chest discomfort include spasm of the esophagus, diseases of the aorta, gastroesophageal reflux disease, musculoskeletal pain, fast heart rhythm abnormalities and costochondritis.What are the limitations of ECG?
5 Limitations of ElectrocardiogramIt cannot provide definite diagnosis of congestive heart failure. Prognosis during anesthesia or surgical procedures is unpredictable. Heart chamber wall thickness cannot be measured. Diseases of heart valves, endocardium, or pericardium cannot be diagnosed.
What can a cardiologist tell from an ECG?

Numerous factors can lead to false-positive and false-negative results, including use of medications, conduction system disease, Left ventricular hypertrophy and other conditions that affect repolarization, valvular heart disease, gender, and testing equipment.What is the 300 rule for ECG?
Simply identify two consecutive R waves and count the number of large squares between them. By dividing this number into 300 (remember, this number represents 1 minute) we are able to calculate a person's heart rate. Rate = 300 / number of large squares between consecutive R waves.Can an ECG rule out angina?

Blood levels of both of these substances become elevated in patients with congestive heart failure.Which lab test is most commonly used to diagnose heart failure?
An echocardiogram is the best test to: Identify which type of heart failure (systolic, diastolic, valvular)What blood tests signal heart failure?
Your doctor may recommend a blood test to check for B-type natriuretic peptide, a protein that the heart secretes to keep blood pressure stable. These levels increase with heart failure. A blood test may also be performed to look for substances that are associated with heart and lung damage.How do I check myself for heart disease?

You can also monitor yourself for symptoms of heart disease, such as: Chest pain, pressure, discomfort, or tightness. Being short of breath.Can an EKG detect an enlarged heart?

Symptoms can develop quickly (acute heart failure) or gradually over weeks or months (chronic heart failure).What are three signs symptoms of angina?
