Left ventricular hypertrophy ecg

Sinus bradycardia: ECG, causes & management Definition of sinus bradycardia Sinus bradycardia fulfills the criteria for • Regular rhythm with ventricular rate slower than 50 beats per minute. • P-waves with constant morphology preceding every QRS complex. • P-wave is positiv in limb lead II. Normal (physiological) causes of sinus bradycardia Sinus bradycardia (SB) is considered a normal finding in the following circumstances: • During sleep. • Well-trained individualsdisplaySB at rest due to high vagal tone. These individuals have developed a highly efficient left ventricle, capable of generating sufficient cardiac output at low heart rates. • During vasovagal syncope (e.g during intense emotional stress) • During vagal maneuvers (Valsalvamaneuver, carotid sinus [baroreceptor]stimulation). • Its not uncommon to discover SB in healthy young individuals who are not well-trained. This is also a normal finding. Abnormal (pathological) causes of sinus bradycardia In all other situations, sinus bradycardia should be regarded as a pathological finding. There are numerous pathological conditions that cause sinus bradycardia. The most important causes are as follows: • Myocardial ischemia/infarction – Particularly ischemia or infarction located to the inferior wall of the left ventricle. This type of bradycardia is due to diminished • • Side effects of drugs (notably beta blockers, digitalis, verapamil, diltiazem, amiodarone, klonidin) – These drugs affect the pacemaker cells in th...

Welcome "What does left ventricular hypertrophy with repolarization abnormality mean? Left ventricular hypertrophy is a thickening of the wall of the heart's main pumping chamber. This thickening may result in elevation of pressure within the heart and sometimes poor pumping action. The most common cause is high blood pressure." — Left ventricular hypertrophy – Symptoms and causes: Have you talked to your doctor about your question or concerns?

Recently, a new ECG criterion, the Peguero-Lo Presti (PLP), improved overall accuracy in the diagnosis of left ventricular hypertrophy (LVH)—compared to traditional ECG criteria, but with few patients with advanced age. We analyzed patients with older age and examined which ECG criteria would have better overall performance. A total of 592 patients were included (83.1% with hypertension, mean age of 77.5 years) and the PLP criterion was compared against Cornell voltage (CV), Sokolow-Lyon voltage (SL) and Romhilt-Estes criteria (cutoffs of 4 and 5 points, RE4 and RE5, respectively) using LVH defined by the echocardiogram as the gold standard. The PLP had higher AUC than the CV, RE and SL (respectively, 0.70 vs 0.66 vs 0.64 vs 0.67), increased sensitivity compared with the SL, CV and RE5 (respectively, 51.9% [95% CI 45.4–58.3%] vs 28.2% [95% CI 22.6–34.4%], p < 0.0001; vs 35.3% [95% CI 29.2–41.7%], p < 0.0001; vs 44.4% [95% CI 38.0–50.9%], p = 0.042), highest F1 score (58.3%) and net benefit for most of the 20–60% threshold range in the decision curve analysis. Overall, despite the best diagnostic performance in older patients, the PLP criterion cannot rule out LVH consistently but can potentially be used to guide clinical decision for echocardiogram ordering in low-resource settings. Population We retrospectively collected data from patients ≥ 70 years old (as of March/31/2018) assisted at our institution—a tertiary care teaching hospital in Sao Paulo, Brazil. From January/...
