What else can I help you with?
Why there is a delay between the heart beat in the blood pressure recording and the heart beat in the electrical ECG?
the ECG signal is traveling faster than the pressure recording wave.
What is R-R interval in an ECG?
the time between the two R waves in ECG
Which part is atrial systole in ECG?
identify the portion of the ECG that represents the electrcal activity associated with atrial systole.
What is a heart attack and what causes a heart attack?
The heart is a muscle, and like all muscles, it needs oxygen to survive. When the blood flow that brings this oxygen to the heart is severely reduced or cut off completely, this causes a heart attack. The blood circulation to the heart is slowed or stopped because of fat, cholesterol, and other substances in the arteries. Together, these substances are called plaque. The process of plaque forming and hardening the arteries is called atherosclerosis. When a piece of plaque breaks off in the arteries, blood clots may form. The narrowed arteries and the blood clots prevent blood from flowing through the heart. The heart is then starved of oxygen and nutrients, and this is called ischemia. This in turn causes damage or death to parts of the heart. The American Heart Association says that every 34 seconds, someone in the US has a heart attack. To prevent a heart attack, you would need to lower your heart attack risk from narrow arteries, being overweight or having high blood pressure.
What does ECG stand for?
Electrocardiogram or electrocardiograph.
What does myocardial ischemia look like on an ECG?
The ECG sign of subendocardial ischemia is ST segment depression. Note that ECG is used more now that EKG.
What does a heart attack look like on a 12 lead ecg?
ST elevation
What happens to the ECG when your heart speeds up?
An ECG stands for an electrocardiogram, a reading of the rhythm of your heart. What happens to the ECG when your heart speeds up is that the reading will change.
What is the difference between ecg and echo?
An ECG or EKG is a recording of the electrical activity of the heart. An echocardiogram is an ultrasound recording of the heart and its blood flow.
What might an abnormal stress test show?
An abnormal electrocardiogram (ECG) may indicate deprivation of oxygen-rich blood to the heart muscle (ST wave segment depression, for example), heart rhythm disturbances
Why there is a delay between the heart beat in the blood pressure recording and the heart beat in the electrical ECG?
the ECG signal is traveling faster than the pressure recording wave.
Why are ECG and pulse rates similar?
both are telling you how often the heart is beating. an ecg simply gives you more information. the spike on an ecg (qrs complex) is the heart contracting an refilling. when you take a pulse, you're feeling the heart beat blood.
You like to read ecg graph how to learn?
yes
What causes ecg changes?
ECG changes can be caused by various factors, including ischemia (reduced blood flow to the heart), electrolyte imbalances, structural heart changes, and conduction abnormalities. Conditions such as myocardial infarction, arrhythmias, and cardiomyopathy can lead to characteristic alterations in the ECG waveform. Additionally, external factors like drug effects, stress, and metabolic disturbances may also contribute to changes in the ECG. Proper interpretation requires consideration of the clinical context and patient history.
What is an ECG and what is it?
An ECG test is a non-invasive procedure that records the electrical activity of the heart at rest. Insight Medical Imaging offers ECG exams on a walk-in basis at most of our locations across Alberta. All ECG exams require a doctor’s requisition, Alberta Health Care card, and photo identification. ECG tests can be used to assess heart rate, rhythm, blood pressure, and other symptoms such as palpitation or chest pain. x-ray.ca/services/walk-in-ecg/
What is abnormal ecg?
An abnormal ECG may indicate some heart problems. It may be an indication of changes in the heart, congenital heart defect, changes in amount of potassium in the blood, heart attack or poor blood supply to the arteries.
Which phase of the ECG indicates ventricular excitation and contraction?
The QRS complex on an ECG indicates ventricular excitation and contraction. It represents depolarization of the ventricles as they prepare to contract and pump blood out to the rest of the body.
