Im a 23 year old guy that used to be very active up until september where i got a racing heart event that really scared me. I also have anxiety so i dont know if it was a very bad panic attack or something else. So since then ive gotten like 10 ekgs, 1 echocardiogram, 1 stress test and 1 echo stress test. My results show thet my RVIDD is 3.2cm or 32mm. On the results it says normal right ventricle size, but everywhere i read online it says that 2.8 is the limit. Why would my doctor say its normal? Imma post the results down below!
Transthoracic Echocardiogram
SUMMARY:
Left ventricle: Systolic function was normal by visual assessment.
Ejection fraction was estimated to be 65 % in the range of 60 % to 65 %.
There were no regional wall motion abnormalities. Wall thickness was at
the upper limits of normal.
INDICATIONS: Palpatation, murmur
PROCEDURE: This was a routine study. The study included complete 2D
imaging, M-mode, complete spectral Doppler, and color Doppler. The heart
rate was 96 bpm, at the start of the study. Systolic blood pressure was
118 mmHg, at the start of the study. Diastolic blood pressure was 74 mmHg,
at the start of the study. Images were obtained from the parasternal,
apical, subcostal, and suprasternal notch acoustic windows. Image quality
was good.
LEFT VENTRICLE: Size was normal. Systolic function was normal by visual
assessment. Ejection fraction was estimated to be 65 % in the range of 60
% to 65 %. There were no regional wall motion abnormalities. Wall
thickness was at the upper limits of normal.
RIGHT VENTRICLE: The size was normal. Systolic function was normal. Wall
thickness was normal.
LEFT ATRIUM: Size was at the upper limits of normal.
ATRIAL SEPTUM: The atrial septum appeared intact.
RIGHT ATRIUM: Size was normal.
MITRAL VALVE: Normal valve structure. There was normal leaflet separation.
DOPPLER: The transmitral velocity was within the normal range. There was
no evidence for stenosis. There was trivial regurgitation.
AORTIC VALVE: The valve was trileaflet. Leaflets exhibited normal
thickness and normal cuspal separation. DOPPLER: Transaortic velocity was
within the normal range. There was no stenosis. There was no regurgitation.
TRICUSPID VALVE: Normal valve structure. There was normal leaflet
separation. DOPPLER: The transtricuspid velocity was within the normal
range. There was no evidence for tricuspid stenosis. There was no
regurgitation.
PULMONIC VALVE: Leaflets exhibited normal thickness, no calcification, and
normal cuspal separation. DOPPLER: The transpulmonic velocity was within
the normal range. There was no regurgitation.
AORTA: The root exhibited normal size.
PERICARDIUM: There was no pericardial effusion.
