I have been suffering from hypertension and immunoglobulin A (IgA) nephropathy for the past many years, which is being treated with tablet Cardace 10 mg, tablet Stamlo 5 mg, tablet Lipitor 10 mg, and fish oil capsules. In addition, I have had a benign prostrate (Grade 2) for the last six years. For the same, I have been taking tablet Urimax 0.40 mg since the previous year and multiple thyroid nodules (largest left & right side 0.81mm x 0.50 cm, no medication). BP is around 130/80 mmHg. My latest blood test results are as follows, Total cholesterol - 155 mg/dl, LDL 95.6mg/dl, Triglycerides 92 mg/dl. FBS 90 mg/dl, Hb1AC 5.7, Sodium 140 mmol/L, Potassium 3.92 mmol/L, Uric Acid 5.9 mg/dl, Calcium 9.3 mg/dl, Phosphorous 3.6 mg/dl, Serum Creatinine 1.22 mg/dl (lab range 0.72-1.20 mg/dl), BUN (blood urea nitrogen) -11.9 mg/dl, Thyroid tests - Free T3 - 3.34 ng/dl, Free T4 - 1.58 n/dl, TSH 0.76 uIU/ml, Haemoglobin - 14.7 gm/dl. I am attaching my latest electrocardiogram (ECG) reports and my previous one from last year. I did an echocardiogram three years back, and the result was normal, with an ejection fraction (EF) of 74 %. My queries on the electrocardiogram (ECG) are as follows. The electrocardiogram (ECG) report mentions sinus tachycardia- is this due to anxiety? I was anxious during the checkup (even a year back) and noticed my increased heartbeats or chest-thumping. My pulse rate is 60 to 75 beats per minute (bpm) as I exercise daily. I have never had any episodes of tachycardia or palpitations regularly. During the recent electrocardiogram (ECG), I took several deep breaths to control my heartbeats, and the technician adjusted the leads a few times while asking me to relax. The recent electrocardiogram (ECG) mentions: Non-specific T-wave abnormality, please explain what this means. The electrocardiogram (ECG) of the previous year noted "non-specific ST-wave abnormality." Why the different comments in the two electrocardiograms (ECGs)? The electrocardiogram (ECG) mentions " occasional premature ventricular contractions (PVC)", was this due to my anxious state and fast pulse rate? I have never had any fainting episodes, feeling of missing a heartbeat, etc. What causes premature ventricular contractions (PVC)? Could my multiple thyroid nodules be a possible cause? Last year the largest nodule was 0.88 x 59 cm on the right side, but this year both the left and right sides had a nodule of 0.81 x 0. 50 cm each. Given the above electrocardiogram (ECG) results for this year and the previous year, please advise if I need to take any further action. Also, my last echo was three years back - when should I take another echo given the electrocardiogram (ECG) results?
