Hello Madam, A very warm welcome to AMD forum. First , I would like to tell you about the concept of Sinus Tachycardia. It is elevated level of heart rhythm with more than 100 beats/min. Normal heart rate ranges from 60-100 beats/min. Sinus tachycardia is usually related to normal physiologic conditions like exercise, stress, fright, anger. Pathologic conditions related to ST are anxiety, fever anemia, hypertension, hyperthyroidism intake of stimulants such as nicotine (smoking), caffeine, drug abuse and acute myocardial infarction etc. In tachycardia, ECG shows normal rhythm but the P-R interval is shortened. P wave is upright if there is no atrial problem. In your ECHO report, ejection fraction is considered normal at range of 55- 65% and even the other parameters (mitral valve) of your EKG are within normal limits http://www.echobyweb.com/htm_level2_eng/normal_parameters_tt.htm. The report also concludes that there is no structural defect like myocardial infarction in the heart. Now as the structural defects are being ruled out by the EKG therefore probable cause of your sinus tachycardia can be increased electrical stimuli due to anxiety, stress, anemia or use of stimulants etc. There is a condition �inappropriate sinus tachycardia or chronic non-paroxysmal sinus tachycardia� in which patients have high resting heart rate and/or amplified heart rate after exercise. Here the patients have no apparent heart disease or other causes of sinus tachycardia. So this can be considered to be due to abnormal autonomic control (abnormal SA node over-activity). http://en.wikipedia.org/wiki/Sinus_tachycardia . In addition, normal Deceleration time is about 200±32ms; values more than 240ms indicate impaired relaxation, and less than 150ms suggest restriction. This prolonged deceleration time shows impaired relaxation which can occur due to ventricular hypertrophy (though your hypertrophy index is within normal limits) or diastolic dysfunction. Therefore now, Valsalva's maneuver, Tissue Doppler imaging or other invasive investigation techniques (if requirement is felt by your cardiologist) can help reach further differential diagnosis with the help of cardiologist. But as we can not examine you personally therefore it is hard to conclude to any specific point. A cardiologist�s opinion can help you further understand the condition. For more information on deceleration time please click this link http://www.anaesthetist.com/anaes/patient/Findex.htm#lusio.htm Until then we would advice you to avoid any stimulants like coffee, alcohol, smoking etc. Avoid any stressful condition and calming yourself with yoga and meditation will help reduce your anxiety and thus sinus tachycardia. Hope this helps. In case of further doubts do write to us at AMD. Take care.

Hi, Welcome to the AMD forum of doctors. The mitral valve deceleration time is a Doppler parameter which is used to assess the diastolic dysfunction of the left ventricle. By diastolic dysfunction, I mean the ability of the left ventricle to relax. The better the left ventricle is able to relax; the better will be its filling during the relaxation phase of the ventricle. The better the filling, the better will be its ability to pump out the blood for all the tissues of the body. Normally, the mitral valve deceleration time is 180-240 ms. However, with worsening diastolic dysfunction, it tends to get prolonged. Although, it�s slightly prolonged in your case, I don�t think it should worry you much as long as all the other parameters of the left ventricle are okay. Normally, this happens only with ageing or with diastolic dysfunction and the common causes of diastolic dysfunction are high blood pressure, diabetes, systemic diseases like amyloidosis, aortic stenosis or cardiac ischemia. But I�ll suggest you to discuss this with your cardiologist as you�re quite young and you should not have the prolonged deceleration time at this age. I sincerely hope that helps. Take care and please do keep me posted in case you have any additional doubts.
