What does electrical alternans indicate?
Electrical alternans is defined as alternating QRS amplitudes in any or all leads on an electrocardiogram (ECG) with no additional evident changes in conduction pathways of the heart. This rhythm is typically associated with pericardial effusion from fluid surrounding the heart.
What are wave alternans?
T-wave alternans is a beat-to-beat alternation of the amplitude and/or shape of the T-wave on the surface ECG. These fluctuations of the T-wave are primary and not related to alternans of other components of the ECG (i.e. QRS alternans).
When do you see Pulsus alternans?
Pulsus alternans is an arterial pulse with alternating strong and weak beats. It is found in the setting of severe ventricular dysfunction and other forms of cardiac pathology.
What is the difference between cardiac tamponade and pericardial effusion?
Pericardial effusion is the technical term for when the pericardium is filling up with fluid. Cardiac tamponade is when pressure from surrounding fluid keeps your heart from beating.
Is electrical alternans seen in cardiac tamponade?
Alternans due to cardiac motion is the most well-known mechanism of electrical alternans, encountered in large pericardial effusions and cardiac tamponade. The pendulous swinging motion of the heart in a fluid-suspended cavity in such situations effectively causes electrical alternans.
What is a Pulsus Paradoxus?
Pulsus paradoxus refers to an exaggerated fall in a patient’s blood pressure during inspiration by greater than 10 mm Hg.
What is a microvolt T wave alternans test?
Microvolt T-wave alternans (TWA) is a noninvasive test of arrhythmia vulnerability. The results of previous observational studies showed that TWA predicts ICD shocks or arrhythmic events in diverse patient populations,12–17 including those with heart failure and ischemic cardiomyopathy.
What is the difference between pulsus alternans and pulsus paradoxus?
Pulsus alternans is a pulse pattern in which there is alternating (beat-to-beat) variability of pulse strength due to decreased ventricular performance. This is sometimes seen in patients with severe CHF. Pulsus paradoxus indicates an exaggeration of the normal reduction of systolic blood pressure during inspiration.
Which is a characteristic of pulsus alternans?
Pulsus alternans is a physical finding characterized by a regular alternation of the force of the arterial pulse. It almost invariably indicates the presence of severe left ventricular systolic dysfunction.
What is Beck’s triad?
The Beck triad (ie, hypotension; elevated systemic venous pressure, often with jugular venous distention; muffled heart sounds) may occur in affected patients, especially from sudden intrapericardial hemorrhage.
What is the difference between pulsus paradoxus and pulsus alternans?
How does COPD cause pulsus paradoxus?
This causes extra pressure to build up in the right side of the heart, which presses against the left side of the heart. All of this results in pulsus paradoxus. In addition, asthma increases negative pressure in the lungs. This puts extra pressure on the left ventricle, which can also cause pulsus paradoxus.
What is a notched T wave?
Notched T waves, also called bifid waves or humps, were defined as a bulge or protuberance just beyond the apex or on the descending limb of an upright T wave.
What is electrical alternans in electrocardiography?
Electrical alternans is defined as alternating QRS amplitudes in any or all leads on an electrocardiogram (ECG) with no additional evident changes in conduction pathways of the heart. This rhythm is typically associated with pericardial effusion from fluid surrounding the heart.
