Ivabradine for inappropriate sinus tachycardia-induced symptomatic Mobitz type I atrio-ventricular block: a case summary.

Background: Inappropriate sinus tachycardia (IST) is characterized by a continuum of symptoms, and the aetiology of IST is imprecise. IST-induced autonomic dysfunction is well known, but IST-induced atrio-ventricular block is not reported to our knowledge.

Case Summary: A 67-year-old female presented with a 4-day history of random intermittent difficulty in breathing, chest tightness, palpitations, and dizziness, with a recorded heart rate of 30 beats per minute (BPM) on home monitoring equipment.

Oxygen Administration under Surgical Face Mask in COVID-19 Patients: A Game Changer.

Unlabelled: COVID-19 is a multifaceted infectious disease. The development of hypoxemic respiratory failure is not uncommon during the course of illness in some of them. The objectives of the present study were to assess the effect of the addition of a surgical face mask while delivering oxygen via nasal cannula in hypoxemic COVID-19 patients and highlight on the advantages and patient's comforts.

Status of Acute Myocardial Infarction in Southern India During COVID-19 Lockdown: A Multicentric Study.

There has been a reduction in the reported cases of acute myocardial infarction (MI) across the globe during the outbreak of coronavirus disease 2019 (COVID-19) (severe acute respiratory distress syndrome coronavirus 2). An attempt was made to find out the number of acute MI cases treated during the COVID-19 lockdown period (April 2020) and highlight the possible reasons for the changes in the occurrence. A multicentric retrospective observational study was performed to collect the selected data from 12 private hospitals distributed in 4 cities-Madurai, Trichy (Thiruchirapalli), Erode, and Salem-of the Tamil Nadu state in southern India.

Not Touching the Face is Harder Than It Sounds: Need for an Intervention.

Unlabelled: In the novel coronavirus (COVID-19) pandemic, preventive medicine has taken center stage, as there is no vaccine or specific antiviral drug regime used to treat patients. Public health authorities and governments are recommending the practice of social distancing and hand hygiene. Hands are a common vector for the transmission of infection, and frequent face touching is extremely common among the public.

Severe hypertension in elapid envenomation.

Snakebite is not an uncommon medical emergency in India; however, symptoms of autonomic dysfunction in snakebite are rare. The elapid snake envenomation is a frequent occurrence in India, and the krait bite is prevalent in the south Indian region. Here, we present three cases of snakebite with severe hypertension and requiring intravenous nitroglycerin (NTG).

Isolated thigh pain in myocardial infarction.

The referred pain of angina to upper half of the body is well known. However, isolated pain in the thigh as a presenting symptom in myocardial infarction is neither considered nor discussed at all. Here, we report a middle-aged man without demonstrable risk factors who presented to the emergency department for isolated bilateral anteromedial thigh pain.

Cardiovascular Complications in Ciguatera Fish Poisoning: A Wake-up Call.

Ciguatera fish poisoning occurs with ingestion of fish containing ciguatoxin. It causes a clinical syndrome that comprises classic gastrointestinal, neurological and cardiovascular symptoms. Ciguatoxin is a sodium channel agonist with cholinergic and adrenergic activity.

Significance of the intima-media thickness of carotid and thoracic aorta in coronary artery disease in the South Indian population.

Background: Ultrasound detected intima-media thickness (IMT) of the carotid artery and thoracic aorta are possible screening tests to assess the risk of coronary artery disease (CAD) in asymptomatic individuals.

Objective: Aim of the study was to assess the utility of carotid and aortic IMT as a predictor of CAD and to assess the extent of IMT with severity of CAD in a South Indian population.

Patients And Methods: A cross-sectional and analytical study was carried out among 40 cases, who had angiographic evidence of CAD against 30 healthy control subjects with a normal treadmill test.

Status of end organs in newly detected rural essential hypertensives: a study from southern India.

Background: Hypertension is associated with end-organ damage (EOD). Since EOD is a risk factor for cardio- and cerebrovascular complications, it is a major requirement for these to be detected, prevented, and treated.

Objective: The objectives of our study were to determine out the prevalence of EOD in newly detected rural essential hypertensives, identify the pattern of EOD involved, and also assess the interrelationship among them.

Acute renal failure in acute poisoning: prospective study from a tertiary care centre of South India.

Background: Cases of people presenting with poisoning are likely to develop acute renal failure (ARF), which may be due to multiple mechanisms/aetiologies. These cases need careful observation and appropriate treatment.

Objective: To find the risk of ARF among acute poisoning cases, identify the underlying causes and to analyse the outcome.
