“…[6] This multiple lobed pattern increases SD1, which has an analogy to HF, [7] therefore HF was increased. These multiple lobes were due to premature atrial contractions [6] in this case, which was also visible in electrocardiography while recording HRV. These premature atrial contractions were intrinsic abnormality of heart which alters the HRV.…”

“…It is because of high SD1 (which is not a real descriptor in case of nonlinear Poincaré plot) that HF is high . It is said that descriptors like SD1, SD2, SDRR, and SDSD rely on fitting of an ellipse to the plot, thus adequate only for a typical elongated torpedo pattern . It can also be stated that HF can be high not only because of parasympathetic activity but also because of intrinsic abnormality of heart like premature atrial contractions, as in this case.…”

“…Thus, accurate classification of Poincaré plot should be done to detect arrhythmias. The texture features of Poincaré plot may provide more insights into understanding the dynamics of heart rhythm during, for example, from normal sinus rhythm to arrhythmic events …”

Hypertension and diabetes mellitus increase chances of cardiovascular morbidity. Premature atrial contractions (PACs) have been shown to be strong and independent predictors of incident atrial fibrillation and associated complications, like stroke and congestive heart failure. These morbidities are diagnosed only when the patient is already suffering from the symptoms. Consequently, it is of paramount importance to develop new techniques for early diagnosis prior to any deterioration on healthy patients. The cardiovascular system is controlled and influenced, apart from a unique intrinsic system, by the autonomic nervous system. In a study, lagged Poincaré plot analysis revealed significant changes suggestive of decreased parasympathetic modulation in diabetic patients. 1 In this case, increased high frequency and SD1 (which usually denote parasympathetic activity) are found, which can be because of premature atrial contractions. | C A S E REP ORTThis is a case of a 63-year-old female presenting with diabetes mellitus, hypertension, hypothyroidism, and postmenopausal osteoporosis. She was admitted to the department of Endocrinology, Dr Ram Manohar Lohia Institute of Medical Sciences, Lucknow on 6/10/19 with complains of fever, breathlessness, anxiety, bodyache, with generalized weakness, anorexia, and insomnia, which improved with medication.She was discharged on 9/10/19 and advised medication paracetamol, metformin 500 mg + glimepiride 3 mg tablet (one tablet BD), sitagliptin 50 mg one tablet BD, Inj Insulin Glargine (24 unit at bed time), (levothyroxine (100 µg one tablet OD), amitriptyline (10 mg one tablet HS), citalopram (10 mg one tablet OD), vitamin D3 (60 000 IU twice a week), and telmisartan, pantoprazole + domperidone (one tablet OD).

Heart rate variability (HRV) is sensitive to the changes of the autonomic activity and decreases in looming morbidity of cardiovascular system due to autonomic dysfunction. In heart block or atrial flutter or atrial tachycardia, HRV with high power reported with cluster pattern on Poincaré plot which could be due to low voltage QRS complex beats which were not picked by software for HRV analysis. Picking those beats using custom settings included the beats and reported true HRV of the patient reflecting autonomic activity.
