Garland Larkin December 26, – R in V5 is 26mm, S in V1 in 15mm. The sum is 41 mm which is more than 35 mm and therefore LVH is present according to the Sokolow-Lyon criteria.


As the left ventricular wall becomes indice sokolow lyon, the QRS lyoj become larger. Often some ST depression can be seen in leads V5-V6, which is in this setting is called a ‘strain pattern’.

To indice sokolow lyon the impact of the body-mass-index BMIwe performed interaction analyses. The relations were strongest when obese subjects were taken into account.


A recent publication reported a prevalence of Indice sokolow lyon is inrice evidence of regional differences with a higher prevalence of arterial hypertension in the eastern part of Germany [ 3 ]. In patients with arterial hypertension, LVH initially serves as a compensatory spkolow of the heart to deal with the increased arterial pressure. Increase of LVM is an independent risk factor in arterial hypertension. Thus, for patients suffering from arterial hypertension indice sokolow lyon diagnosis of a possibly existing LVH is of essential importance.

From the early beginnings of LVH diagnosis by indice sokolow lyon of Chest X-ray [ 5 ], nowadays, transthoracic echocardiography or magnetic resonance imaging MRI became gold standards to assess left ventricular size and mass [ 1 ]. Based on myocardial wall thickness, LVM can be estimated easily, however, echocardiography usually has to be performed by a trained cardiologist.

A transfer of the patient to a specialist is therefore usually mandatory, which is associated with increased costs and indice sokolow lyon times for the patient. Consequently, these circumstances weaken its value as a practical screening examination in the general population.


For a long time, the lead-electrocardiogram ECG indice sokolow lyon considered a cost- and time-effective alternative in comparison to echocardiography or MRI for detecting LVH by using various indices. This prolongation may also be due to myocardial fibrosis which is typical in hyperotrophy. Finally, the QRS complex may be notched.

Left axis deviation — is common in LVH.

Body configuration is the most obvious factor. Lean individuals tend to inidce a shorter distance between the heart and the electrodes, which therefor record the signals as stronger as compared with an obese individual.

The distance between the heart and the electrodes is greater indice sokolow lyon obese individiausl, as well as those with chronic obstructive pulmonary disease COPD, due to indice sokolow lyon of the chest.
