right-ventricular hypertrophy
1.the position of the electrical axis is changed: in right-ventricular hypertrophy dextogram;
2.In right-ventricular hypertrophy the changes in the S and R waves are the reverse:
high R wave ≥ 7 mm appears in V1-2, deep S wave in V4-6 .
Right ventricular hypertrophy options
1-st type - R-type
2- st type - rSR -type
3- st type - S –type (rSr)
right-ventricular hypertrophy R-type
right-ventricular hypertrophy: rSR -type
right-ventricular hypertrophy: S –type
Hypertrophy of auricles is determined by changes of P-wave.
Left atrium hypertrophy is |
|
detected by “P mitrale”: wide |
|
(>0.1 s), |
|
splitted Р-wave in I, II, AVL, left |
I |
chest leads (V5-6); flat or |
|
negative Р in III, |
|
biphasic or negative (>1 mm) |
|
Р in V1 |
|
Left atrium hypertrophy is |
III |
typical in mitral valves diseases |
|
(mitral stenosis and mitral |
|
incompetence). |

Left atrium hypertrophy
Left atrium hypertrophy
Right atrium hypertrophy is detected by “P pulmonale”: high (>2.5 mm) acute Р in II, III, AVF and right chest leads (V1- 2).
Right atrium hypertrophy is typical in chronic pulmonary diseases (pulmonary heart) and tricuspid valves incompetence.
II, III, AVF
