S3 Gallop

Ventricular Gallop


Presentation

  • All the examiners were able to significantly alter the prior odds of an apical S3 gallop's being present, but the cardiology fellows had higher sensitivities.[ncbi.nlm.nih.gov]
  • This heart sound when present in a child or young adult implies the presence of a supple ventricle that can undergo rapid filling.[popflock.com]
  • A pathologic presentation occurs more often in older individuals in volume-overloaded states, such as heart failure. This diastolic gallop is produced by rapid deceleration of transmitral blood flow as it strikes a noncompliant left ventricle.[link.springer.com]
  • When present, valvular disease is more likely to be severe [ 3 ]. Prevalence Physiologic S3 is uncommon after 35–40 years of age [ 1 ].[thoracickey.com]
  • Dilated LV (S3 Present) S3 is a low-pitched sound; this is helpful in distinguishing a S3 from a split S2, which is high pitched.[healio.com]
Noncompliance
  • The sound of the S3 gallop, which immediately follows the second heart sound (S2) is thought to be produced by the sound of blood flowing into a noncompliant ventricle .[tititudorancea.com]
  • This diastolic gallop is produced by rapid deceleration of transmitral blood flow as it strikes a noncompliant left ventricle. The change in velocity causes reverberations that produce the sound.[link.springer.com]
  • Noncompliant left ventricle. Restrictive filling characteristics. Reduced LV systolic function (also in diastolic dysfunction). When present, valvular disease is more likely to be severe [ 3 ].[thoracickey.com]
  • S 3 occurs in early diastole, when the ventricle is dilated and noncompliant.[merckmanuals.com]
  • Other Abnormal Heart Sounds opening snap is caused by a noncompliant valve, such as a mitral valve in a patient with a history of rheumatic fever ejection click is a high-pitched sound occurring shortly after S1.[chfpatients.com]

Left Ventricular Dysfunction
  • Most often an S3 is a sign of reduced left ventricular ejection fraction and therefore left ventricular dysfunction.[link.springer.com]
  • Effect of captopril on mortality and morbidity in patients with left ventricular dysfunction after myocardial infarction: results of the survival and ventricular enlargement trial. ‎ Seite 248 - Group.[books.google.de]
  • Vital signs usually include a low blood pressure, tachycardia, and pulsus alternans, a pulse that alternates strong and weak beats and usually happens in patients with severe left ventricular dysfunction.[acphospitalist.org]
  • S 3 , with or without S 4 , is usual in significant systolic left ventricular dysfunction; S 4 without S 3 is usual in diastolic left ventricular dysfunction.[merckmanuals.com]
  • In patients with aortic valve regurgitation, S3 indicates left ventricular dysfunction and may be useful for selecting patients for heart cath and valve replacement. A persistent S3 after heart attack indicates a poor prognosis.[chfpatients.com]
Increased Jugular Venous Pressure
  • jugular venous pressure, rales, hepatomegaly, S3 gallop , blood pressure, with a measured blood volume.[freethesaurus.com]
Hepatosplenomegaly
  • Right-sided S3 is accompanied by the constellation of findings classically seen in right-sided heart failure: hepatosplenomegaly, peripheral edema, pleural effusions, and ascites.[thoracickey.com]
Hysteria
  • […] abuse, especially methamphetamine, and egg donation Additional maneuvers include the scapulohumeral reflex, the head thrust test, the apprehension test, and a newly described test for intercostal muscle innervation Additional information on dementia, hysteria[books.google.de]
Dyslexia
  • I just seem to have some dyslexia about how the heart works. I am working on it daily and trying to figure it out in a way I can understand. So in the CCS book by conrad fisher, he writes a sentence that confuses me.[usmleforum.com]

Workup

  • Workup is focused on identifying any possible reversible causes. Recommended laboratory testing includes thyroid function tests, HIV serology, electrolytes, and iron studies (to rule out hemochromatosis).[statpearls.com]
Absent A-Waves
  • This indicates slow filling caused by older age, hypertension, left ventricular hypertrophy (LVH), or diastolic dysfunction. exaggeration of normal – a tall, thin E wave with a small or absent A wave.[thoracickey.com]

  • In most cases, loud S3 quickly becomes soft or even disappears after few days of treatment with diuretics and dyspnoea's regression.[cardiacauscultation.com]
  • Treatment is aimed at alleviating the underlying disease process through medical or surgical intervention.[link.springer.com]
  • Treatment The condition itself does not need to be treated, but rather the underlying cause requires correction. Depending on the etiology the gallop rhythm may resolve spontaneously. See also Alexander George Gibson Arthur D.[popflock.com]

Prognosis

  • Similarly, the prognosis for a heart failure patient with an S3 is worse. Treatment is aimed at alleviating the underlying disease process through medical or surgical intervention.[link.springer.com]
  • Overall, the prognosis of patients with dilated cardiomyopathy is guarded.[statpearls.com]
  • In a study of patients awaiting heart transplant , an S3 was one of 7 risk factors predicting a poor prognosis.[chfpatients.com]

Etiology

  • Depending on the etiology the gallop rhythm may resolve spontaneously. See also Alexander George Gibson Arthur D.[popflock.com]
  • Etiology There are two phases of ventricular filling. To start the first phase, ventricular blood pressure drops sufficiently to allow the opening of the AV valves. Blood rapidly flows from the atrium to the ventricles comprising 80 % of filling.[thoracickey.com]
  • Primary DCM is considered idiopathic and the diagnosis can only be made after excluding secondary causes. [1] [2] [3] Etiology The most common etiology of dilated cardiomyopathy (DCM) is idiopathic and without an identifiable cause.[statpearls.com]
  • Regarding imaging, the echocardiogram is the single most useful test in evaluating the etiology of heart failure, Dr. Navas said, but she also reminded attendees that it can be overused.[acphospitalist.org]
  • Depending on the etiology the gallop rhythm may resolve spontaneously. See also [ edit ] Alexander George Gibson Arthur D.[en.wikipedia.org]

Epidemiology

  • It is characterized by transient ballooning of the left ventricular (LV) apex typically following a severe psychological or physiological stress that is believed to be secondary to intense catecholamine surge. [4] Epidemiology DCM is more commonly seen[statpearls.com]
