Prognosis
The prognosis associated with myocarditis is stratified by the severity and time course along which symptoms develop. In addition to symptom severity, there are also several indicators of heart function that can be used to predict patient outcomes, many of which are part of the standard evaluation of patients presenting with cardiovascular dysfunction. An electrocardiogram is one of the most common screening tools used in cases of suspected cardiac pathology, such as myocarditis. The findings that correlate with poorer outcomes are non-specific and include widened QRS complexes and QT intervals, partial or complete atrial-ventricular heart block, and malignant ventricular arrhythmias like sustained ventricular tachycardia or ventricular fibrillation. Electrocardiogram findings of ST elevations with upward concavity and an early repolarization pattern, however, were associated with a better cardiovascular prognosis in general.In cases of acute myocarditis, cardiac magnetic resonance imaging can reveal several prognostic indicators that, similar to ECGs, are non-specific and reflect poorer cardiac physiology. Late gadolinium enhancement on cardiac MRI demonstrates perturbations in extracellular volume as a result of cell necrosis or edema, and is significantly associated with increases in all-cause mortality, cardiovascular mortality, and major adverse cardiovascular events. The association was strongest with any late gadolinium enhancement, but remained true for findings of anterolateral-specific enhancement.
Braxton Hicks contractions, also known as practice contractions or false labor, are sporadic uterine contractions that may start around six weeks into a pregnancy. However, they are usually felt in the second or third trimester of pregnancy. Associated conditions
Braxton Hicks contractions are often confused for labor. Braxton Hicks contractions allow the pregnant womans body to prepare for labor. However, the presence of Braxton Hicks contractions does not mean a woman is in labor or even that labor is about to commence. Another common cause of pain in pregnancy is round ligament pain. Table 1. Braxton Hicks contractions vs. True Labor

Pathophysiology
Although the exact causes of Braxton Hicks contractions are not fully understood, there are known triggers that cause Braxton Hicks contractions, such as when a pregnant woman:
is dehydrated
has a full bladder
has just had sexual intercourse
has been exercising (running, lifting heavy objects)
is under excessive stress
has had her stomach touchedThere are two thoughts for why these intermittent uterine muscle contractions may be occurring. The first is that these early “practice contractions” could be helping to prepare the body for true labor by strengthening the uterine muscle. The second is that these contractions may occur when the fetus is in a state of physiological stress, in order to help provide more oxygenated blood to the fetal circulation. Signs and symptoms
The determination of Braxton Hicks contractions is dependent on the history and physical assessment of the pregnant womans abdomen, as there are no specific imaging tests for diagnosis.
