ChildFemaleThis 11-year-old previously healthy female began having syncopal episodes at rest and during exertion. Baseline ECG (PR interval = 155, QRS duration = 85, and QTc = 389 ms) and echocardiogram were normal. During 24-hour ambulatory heart rhythm monitoring, there were several episodes...
ECGs can help medical professionals identify and/or monitor multiple types of heart conditions, includingarrhythmias, blocked arteries, heart failure, heart attacks, and damage to the heart. Usually, an ECG is used when someone shows symptoms of a heart problem, such as chest pain, dizziness, fa...
Anyone aged 40 years or older should have an ECG done. This first ECG serves as a screening tool to detect any cardiac problems and as a baseline for comparison of futureECGs. A complete list of who should obtain an ECG, called Guidelines forECG, is published by the Joint Committee of t...
Fill in the blanks. When the ECG tracing shows only ventricular tachycardia, it is called ___ or ___. What is a normal baseline fetal heart rate? What is hypertrophy of the heart? What is a typical resting heart rate? What occurs...
Long covid (post covid-19 condition) is a complex condition with diverse manifestations, uncertain prognosis and wide variation in current approaches to management. There have been calls for formal quality standards to reduce a so-called “postcode lottery” of care. The original aim of this stu...
What is the function of the mitral and tricuspid valves? Define the following cardiovascular term: "cardiac catheterization". What does the heart have to do to compensate for a hole between the two ventricles? How does the ECG vary and what is occurring during these conditions: junctional rhythm...
Yes. ECG can detect a heart problem that might lead to a stroke or even uncover a past problem such as a previous heart attack. Such ECG results would be classified as abnormal ECG. Often ECG is the prefered method to detect these problems and is frequently used, for example, to confirm...
Blood pressure is measured using a sphygmomanometer, which consists of an inflatable cuff and a measurement device. The cuff is wrapped around the upper arm and inflated, restricting blood flow. As the cuff deflates, the device measures the pressure exerted on the artery walls, giving readings ...
What is a normal baseline fetal heart rate? In sinus tachycardia, the heart rate is between and ___ and ___ beats per minute. What neurotransmitter slows heart rate? Which of the following ECG tracings represents electricity flowing over the ventricles? a. P wave b. QRS wave c. T wave...
Baseline wander in ECG signals Stray (intransitive) To wander, as from a direct course; to deviate, or go out of the way. Wander To ramble here and there without any certain course or with no definite object in view; to range about; to stroll; to rove; as, to wander over the fields...
