Over the past six decades, echocardiography has evolved into an important technique for not only imaging cardiac structures, but also, by employing the Doppler equation, for assessing cardiac blood flow and tissue velocities. This review focuses on pulsed Doppler echocardiography: its principles, early development, and clinical applications. Important clinical applications include: (1) measurement of flow velocities, stroke volumes, and regurgitant and shunt volumes; (2) assessment of time intervals, e.g., pulmonary artery acceleration time as a measure of pulmonary artery pressure and resistance or the timing of mitral regurgitation in hypertrophic cardiomyopathy; (3) detection of turbulent flow in regurgitation, stenoses, and shunts, enhanced by the implementation of color Doppler; and (4) evaluation of left ventricular diastolic function in conjunction with pulsed tissue Doppler and deformation (strain) measurements.

In the late 1940s, amid elevated concern about heart disease and new funding to fight it, multiple screening emerged alongside group psychotherapy for weight loss as two innovative responses of the American public health community. I describe the early trajectory and fate in the 1950s of both programs as shaped by the ongoing political controversy about national health insurance. Group weight loss became the main de facto American response to a perceived obesity-driven heart disease crisis. The episode casts light on the larger picture of how postwar American public health gravitated toward interventions centered on individual behavior and may offer lessons for obesity interventions today.

Conception, development, innovation, introduction, and validation are some of the steps in the introduction of new technologies and their clinical applications. More than 50 years ago, Doppler techniques and applications were introduced into echocardiography. An important further addition was the introduction of color as a medium for the display of Doppler information. The amplitude of the returning ultrasound signal has been used to generate a black and white image of structure. The phase shift between the transmitted and returning Doppler signal has been used to display Doppler shift information in color. This review focuses on some of the resources critical to this new development, the challenges imposed by the introduction of a new color display, and some of the early clinical validation and applications of color Doppler echocardiography.

Lovesickness has been termed a real disorder, with a specific cause, pathogenesis, and cure: it has been attested to in the medical literature since classical times and may still have a place in current medicine in the frame of psychiatry and humoral disorders. Although in different cultures there is a general agreement on the symptoms, including fever, agitation, loss of appetite, headache, rapid breathing, and palpitations, the treatments vary greatly in the various cultural contexts.
