Pregnancy May Affect the Attenuation of an ST Segment Elevation in the Right Precordial Leads: A Female Patient with Brugada Syndrome.

Pregnancy May Affect the Attenuation of an ST Segment Elevation in the Right Precordial Leads: A Female Patient with Brugada Syndrome. Intern Med. 2019;58(21):3099-3102 Authors: Ideishi A, Ogawa M, Nagata Y, Idemoto Y, Komaki T, Morii J, Saku K, Miura S Abstract A 30-year-old woman was referred to our hospital to undergo an evaluation for suspected Brugada syndrome. She showed no symptoms, but had a strong family history of sudden cardiac death. During observation, Holter electrocardiography (ECG), which had been performed to investigate her symptoms of occasional dizziness, showed a sinus node dysfunction with an occasional long sinus pause. An implantable cardioverter defibrillator (ICD) was therefore put in place, and bradycardia pacing from the ICD relieved those symptoms during the subsequent 18-month follow-up. The patient completed two pregnancies during the follow-up period. No symptomatic changes occurred during the pregnancies, but ECG indicated that an ST segment elevation in the right precordial leads was attenuated during the second and third trimesters of both pregnancies.

CONCLUSIONS: LA is a safe and effective tool in HoFH subjects even in pregnancy. Evidence based guidelines for the management of these patients during pregnancy are still lacking. PMID: 31818440 [PubMed - in process]

A 26-YEAR-OLD gravida 2 at 38 weeks gestation was scheduled to undergo emergency lower segment cesarean section (LSCS). She had a known case of double outlet right ventricle (DORV). She had undergone a bidirectional Glenn (BDG) shunt at the age of 3 years. Her first pregnancy resulted in a preterm vaginal delivery, with the child dying on the 5th postpartum day. She was taking oral metoprolol, 50 mg, and torsemide, 5 mg, daily. In the operating room, her hemodynamics were as follows: initial heart rate 106 beats per minute, blood pressure 130/80 mmHg, sinus rhythm on electrocardiogram, and oxygen saturation 88% in room air.

Monitoring fetal heart rate during pregnancy is essential to assist clinicians in making more timely decisions. Non-invasive monitoring of fetal heart activities using abdominal ECGs is useful for diagnosis of heart defects. However, the extracted fetal ECGs are usually too weak to be robustly detected. Thus, it is a necessity to enhance fetal R-peak since their peaks may be hidden within the signal due to the immaturity of the fetal cardiovascular system. Therefore, to improve the detection of the fetal heartbeat, a novel fetal R-peak enhancement technique was proposed to statistically generate the weighting mask accordin...

Rationale: Coronary angiography (CAG) findings of acute myocardial infarction (AMI) in pregnant women are characterized by a high incidence of normal coronary arteries. This is the first report of AMI with normal coronary arteries during pregnancy, showing coronary spasm and pregnancy-related acquired protein S (PS) deficiency. Patient concerns: A 30-year-old Japanese woman was admitted to an emergency department. One hour before admission, she developed sudden onset of precordial discomfort, back pain, and dyspnea. She was a primigravida at 39 weeks’ gestation and had no abnormality in the pregnancy thus far. S...

This is written by Brooks Walsh. 30 year-old woman was brought to the ED with chest pain.It had started just after nursing her newborn, about an hour prior, and she described it as a severe non-pleuritic “pressure” radiating to the back.She had given birth a week ago, and she had similar chest pain during her labor. She attributed the chest pain to anxiety and stress, saying " I'm just an anxious person. "A CXR and a CTA for PE were normal.The ECGsAn initial ECG was obtained as the pain was rapidly resolving:Minimal upsloping ST Elevation in III, with a steeply biphasic...

We describe the case of a 32-year-old parturient with end-stage renal disease on hemodialysis with superimposed preeclampsia who developed clinically significant hyperkalemia with electrocardiographic changes after magnesium infusion. The magnesium infusion was stopped, and the patient underwent emergent hemodialysis with subsequent improvement. Hyperkalemia caused by magnesium infusion is a rare and not very well-understood phenomenon.

A 40-year-old woman at 34 weeks of gestation complained of shortness of breath upon exertion. An electrocardiogram revealed broad ST elevation, and echocardiography showed diffuse impairment of left ventricular contractility. The patient was immediately transferred to our hospital for suspected ...

AbstractKey contentPalpitations are common in pregnancy. While they are frequently benign, some will represent a significant arrhythmia.Pregnant women presenting with palpitations require a careful assessment to determine whether their symptoms can be attributed to normal physiology or require further investigation for pathology.Management of pre ‐existing arrhythmias in pregnancy requires a multidisciplinary team approach.Most anti ‐arrhythmic treatments are safe in pregnancy, and prompt, effective treatment of pathological arrhythmias should be instigated without delay.Learning objectivesTo identify which women prese...

Peripartum cardiomyopathy (PPCM) is a potentially life ‐threatening condition typically presenting as heart failure with reduced ejection fraction (HFrEF) in the last month of pregnancy or in the months following delivery in women without another known cause of heart failure. This updated position statement summarizes the knowledge about pathophysiolo gical mechanisms, risk factors, clinical presentation, diagnosis and management of PPCM. As shortness of breath, fatigue and leg oedema are common in the peripartum period, a high index of suspicion is required to not miss the diagnosis. Measurement of natriuretic peptides,...
