I had to emergency ecg n echo today due to sudden chest discomfort going down left arm and dizziness. Ecg was okay but echo not Plz explain diastolic dysfunction grade 1? Is it serious plz note I was in sinus tachycardia during echo! Does e n a waves merge and give false readings in that case? My deceleration time is 183 msec- very well within normal limits and ejection fraction is also fine Can heart which cant relax properly pump out blood so well? When shud I get it done again? Doctor said symptoms are from cervical spondylitis n not heart
