Echocardiography

M-mode
- details changing motion of structures along the ultrasound beam with time
- assess LV wall and cavity dimensions, pericardial thickness


2-dimensional echo
- assessment of ventricular volumes and ejection fraction; delineation of specific anatomy of cardiac structures including valves


Pulse doppler echocardiography
- assess diastolic function and dysfunction by assessing transmitral flow velocities, differentiate between constrictive and restrictive cardiomyopathy

Continuous wave doppler
- assess transvalvular pressure gradients, to estimate severity of stenotic lesions (which causes increased velocities)

Color doppler
- assess severity of valvular regurgitations

I was diagnosed as HEPATITIS B carrier in 2013 with fibrosis of the
liver already present. I started on antiviral medications which
reduced the viral load initially. After a couple of years the virus
became resistant. I started on HEPATITIS B Herbal treatment from
ULTIMATE LIFE CLINIC (www.ultimatelifeclinic.com) in March, 2020. Their
treatment totally reversed the virus. I did another blood test after
the 6 months long treatment and tested negative to the virus. Amazing
treatment! This treatment is a breakthrough for all HBV carriers.
