Ventricular flutter is an arrhythmia, more specifically a tachycardia affecting the ventricles with a rate over 250-350 beats/min, and one of the most indiscernible. It is characterized on the ECG by a sinusoidal waveform without clear definition of the QRS and T waves.
The main symptom of AVNRT is the sudden development of rapid regular palpitations. [1] These palpitations may be associated with a fluttering sensation in the neck, caused by near-simultaneous contraction of the atria and ventricles against a closed tricuspid valve leading to the pressure or atrial contraction being transmitted backwards into the venous system. [2]
A normal resting heart rate is 60 to 100 beats per minute. A resting heart rate of more than 100 beats per minute is defined as a tachycardia. During an episode of SVT, the heart beats about 150 to 220 times per minute. [9] Specific treatment depends on the type of SVT [5] and can include medications, medical procedures, or surgery. [5]
Treatment depends on the type of heart rhythm shown on an electrocardiogram test, and the stability of the patient's blood circulation. If a patient has low blood pressure, difficulty breathing, chest pain, shock, or confusion, they are considered unstable and must have an electrocardiogram result checked to determine if the heart is beating ...
Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome [4] [5] Other presenting signs or ...
De Musset's sign is a type of rhythmic bobbing of the head in synchrony with the beating of the heart, seen in severe aortic regurgitation. [1]This sign occurs as a result of blood from the aorta regurgitating into the left ventricle due to a defect in the aortic valve.
Sometimes, checking the heart's structure is also important. Most people with palpitations have a normal heart. But, there may be issues, like valve problems, in some cases. In these cases, a doctor may hear a murmur and perform an ultrasound of the heart, called an echocardiogram. This test uses sound waves to create images of the heart.
Atrial flutter is characterized by a sudden-onset (usually) regular abnormal heart rhythm on an electrocardiogram (ECG) in which the heart rate is fast. Symptoms may include a feeling of the heart beating too fast, too hard, or skipping beats , chest discomfort, difficulty breathing , a feeling as if one's stomach has dropped, a feeling of ...
