Difference Between Arythmia An Palpitations
Arrhythmia: Tachycardia is a general term applied to any fast heart rate including tachyarrhythmias. A tachyarrhythmia specifically implies a form of arrhythmia which causes a fast heart rate, not all arrhythmias cause a fast heart rate. Tachycardia is defined as a heart rate more than 100, normal heart rhythm is frequently more than 100 in exercise, excitement, fevers, etc. None of these are arrhythmias. ...Read more
Palpitations are an awareness of extra heartbeats which most of us have. The sensation can be single or multiple and can sometimes last minutes. Different people may feel other symptoms along with them such as dizzy, lightheaded or short of breath. The palpitations are almost always atrial or ventricular premature beats. Usually benign but they are also ...Read more
Everything: Svt arises in the atria (the upper chambers) and VT arises in the ventricles (lower chambers). Svt often occurs in otherwise healthy hearts and is annoying but only rarely serious. Vt usually arises in diseased hearts, can be serious, and sometimes is life-threatening. Vt in the setting of a heart attack or acute coronary syndrome is very dangerous. ...Read more
Sensation vs. Rhythm: Palpitations are the sensation of skipping or abnormal heart beats. These might be from abnormal beats, or just the normal rhythm beating fast or stronger than normal. Heart arrythmias are actual, documented (by ekg, holter, event monitor) abnormal heart contractions. ...Read more
How an EKG looks: Cardiac arrest refers to any situation in which the heart is not pumping blood. This may occur with abnormal electrical activity in the heart in which the heart is quivering ( ventricular fibrillation) or beating so fast in can not pump blood effectively (ventricular tachycardia, ) asystole is a kind of cardiac arrest in which the heart is electrically silent ( flat line) on ekg. ...Read moreSee 2 more doctor answers
Difference between paroxysmal arrhythmia and atrial fibrillation? Difference between paroxysmal arrhythmia and atrial fibrillation? I'm trying to understand the difference between the two. Can someone help me?
Some overlap: A paroxysmal arrhythmia is one that is not present constantly. There are several abnormal rhythms that can be paroxysmal including atrial fibrillation. Alternatively atrial fibrillation can be present continuously, in which case it is not paroxysmal. ...Read moreSee 1 more doctor answer
Yes.: These are two different rhythms. Atrial tachycardia is an abnormal rhythm originating from either the left or right atrium. Junctional tachycardia is an abnormal rhythm originating from the av node. Neither is more dangerous than the other. The treatments will be different, usually. ...Read moreSee 1 more doctor answer
Common problems: A heart murmur is blood flow that can be heard with a stethoscope. This can be normal flow or abnormal flow. Tachycardia is the finding of a heart rate above the normal resting heart rate for your age. Arrhythmia is defined as the electricity moving through the heart in an abnormal pattern. There are many types of arrhythmia, some benign and some serious. ...Read moreSee 1 more doctor answer
No, technically yes: They both indicate an irregularity of your heart's rhythm. If you listen at your chest, you actually hear the heart beats. If you check a peripheral pulse, you're feeling the momentary arterial bulge that results from the heart beat. Special case: in atrial fibrillation, the pulse rate will always be "slower" than the hr because some beats aren't transmitted. ...Read more
Don't guess: If you think you could be having cardiac problems this needs to be evaluated. Medical causes for symptoms should be ruled out before making diagnosis. Panic attacks sxs: anxiety; rapid, pounding heart; chest tightness/pain; shortness of breath w hyperventilation; hot /cold flashes; butterflies in stomach, nausea or vomiting; tingling of mouth or extremities; ^ sweating; feeling faint or > ...Read more
Organization: Atrial flutter is a very organized rhythm in which electricity gets stuck in a loop going round and round, much like cars on a nascar racetrack. Atrial fibrillation is a more complex rhythm, in which the majority of the atrium is in chaos, driven by a focus known as a rotor. Atrial fibrillation is much harder to cure than atrial flutter, however rate control is usually better for fibrillation. ...Read moreSee 1 more doctor answer
Bottom and top: Ventricle is the bottom part of the heart, or the main pumping chamber. Rhythms that start here are not normal, and in some situations can be fatal. Rhythms that originate anywhere else are called supraventricular. While less associated with sudden death, are still not good when sustained. ...Read moreSee 1 more doctor answer
Mechanisms vary: Bradycardia simply means slow heart beat. Sinus bradycardia refers to a specific cause for the slow heart beat which is sluggishness of the natural pacemaker cells of the heart (referred to as sinus node). This could be normal in physically fit people or abnormal especially if associated with symptoms of fatigue, shortness of breath or passing out spells. ...Read more
