Athletes´ Heart: QTc Dispersion and Speckle Tracking Echocardiography

Cardiac Mechanics Evaluated by Speckle Tracking Echocardiography

Natural myocardial markers, or speckles, originated from constructive and destructive interference of ultrasound in the tissues may provide early diagnosis of myocardial changes and be used in the prediction of some cardiac events. Due to its relatively temporal stability, speckles can be tracked by dedicated software along the cardiac cycle, enabling the analysis of the systolic and diastolic ...

Endurance and Strength Athlete's Heart: Analysis of Myocardial Deformation by Speckle Tracking Echocardiography

BACKGROUND Intensive training induces two morphological myocardial typologies of athlete's heart. Endurance training (ET) induces eccentric remodeling, bradycardia and better diastolic filling. Strength training (ST) determines concentric chamber remodelling maintaining a normal heart rate (HR). Aim of the study was to compare ET and ST athletes' heart using speckle tracking echocardiography (S...

Interatrial block and atrial remodeling assessed using speckle tracking echocardiography

BACKGROUND To evaluate the possibility of left atrial (LA) remodeling using speckle tracking echocardiography (STE) in patients with interatrial block (IAB). METHODS We performed a cross-sectional study with three groups of patients: 56 without IAB, 21 with partial IAB (pIAB), and 22 with advanced IAB (aIAB). Transthoracic echocardiographic (TTE) STE was performed and clinical and echocardiog...

WSTĘP Wizualna ocena zaburzeń kurczliwości to jedno z trudniejszych zagadnień echokardiograficznych, wymagające dużego doświadczenia. Półilościowa ocena kurczliwości związana bywa z różnicami w interpretacji między ekspertami oraz ze zmiennością interpretacji nawet przez tego samego echokardiografistę. Krokiem ku obiektywizacji oceny regionalnej funkcji skurczowej jest wprowadzenie technik iloś...
