Done ECG And ECHO. What Do Results Indicate?

ECG Results and Echo results- what does this mean, should I be doing something else? I have a family history of heart diseas and just found out my sister has an ASD at teh age of 47.

Ventricular Rate 48 BPM
Atrial Rate 39 BPM
QRS Duration 66 ms
QT 490 ms
QTc 437 ms
R Axis 24 degrees
T Axis 64 degrees
-------------------------------------------

Junctional rhythm
T wave abnormality, consider anterior ischemia
Abnormal ECG
When compared with ECG of 26-AUG-2012 22:08,
Junctional rhythm has replaced Sinus rhythm

Transthoracic Echocardiogram
ECHOCARDIOGRAPHIC MEASUREMENTS:
Diastolic Diameter: 4.8 cm (3.5-5.5 cm) Aortic Root: 2.7 cm (2.0-3.7 cm)
Systolic Diameter: 3.0 cm (2.5-4.0 cm) Left Atrium: 3.7 cm (1.9-3.8 cm)
Septal Thickness: 0.7 cm (0.7-1.2 cm)
Post. Wall Thickness: 0.9 cm (0.7-1.1 cm) EF%: 55-60(55-75%)

REFERRING DIAGNOSIS: Edema

Height = 67" Weight = 182 lbs BSA = 2.0 m2 Resting Blood Pressure = 150/81 mmHg


TWO DIMENSIONAL ECHOCARDIOLOGY:
This was a technically difficult study. Left ventricular size is normal.
Left ventricular wall thickness is normal. Segmental left ventricular
function is normal. Overall left ventricular function is normal with an
estimated ejection fraction of 55-60 %. Right ventricular size is borderline
dilated. Right ventricular wall thickness is normal. Right ventricular
function is normal. Left atrial size is normal. The left atrial volume index
is 26 ml/m2 (normal < 29, moderately dilated 34-39, severely dilated > 39).
Right atrial size is mildly enlarged. The pulmonary artery size is normal.
The aortic root size is normal. The aortic valve is normal. The mitral valve
is normal. The tricuspid valve is normal. The pulmonic valve is normal. No
pericardial effusion is seen. Normal saline contrast injection without
evidence of right to left intracardiac or intrapulmonary shunt. The
pericardial space is echodense suggestive of prominent epicardial fat,
echodense effusion, or infiltrative process.

SPECTRAL DOPPLER:
There is trace mitral regurgitation. There is trace tricuspid regurgitation.
The peak tricuspid regurgitant velocity is 2.2 m/sec. With an assumed right
atrial pressure of 10 mmHg, the estimated pulmonary artery systolic pressure
is 29 mmHg.

COLOR FLOW DOPPLER:
There is trace mitral regurgitation. There is trace tricuspid regurgitation.

FINAL IMPRESSIONS:
01) Technically difficult study.
02) Normal left ventricular size. The left ventricle has normal systolic
function.
03) Borderline dilated right ventricle. Right ventricular wall thickness is
normal. The right ventricle has normal function.
04) LA volume index is 26 ml/m2 (normal
severely dilated > 39).
05) Mild right atrial enlargement.
06) Normal saline contrast injection without evidence of right to left
intracardiac shunt.
07) The pericardial space is echodense suggestive of prominent epicardial
fat, echodense effusion, or infiltrative process.
